Base: Improve some application man pages

- FontEditor.md
- Magnifier.md
- Presenter.md
- Terminal.md

Where an arrow is indicated by -> turn it into an actual arrow →
(U+2192 Rightwards Arrow). This looks much neater.
Inspired by Notion doing this automatically when you type "->".

I've made various corrections: fixing grammatical errors, removing
unnecessary or adding-in missing spaces. Made the style of references
to menu items more consistent. Generally I've tried to make the pages
read better. Terminal has had more adjustment than the others as its
Settings were recently changed and the man page now reflects this.

+The Toolbar contains the same functional entries as that of the Menubar and is represented as clickable icons. Hovering on each icon will display additional information listed in the status bar which further states what each icon does.
 
 ### The Main Workspace
 The main workspace has three partitions:
 
-- The ***left section*** contains the glyph editor window. This window has three different zoom factors for ease of use and for your viewing comfort. They are 500%, 1000% and 1500%. You can freely switch to any zoom level at anytime while creating your font. Don't let the size of the glyph editor window fool you. This is where you will spend about 95% of the time. And the task is that of shaping each glyph by left+clicking on the mouse. You can form a dot, a line, or a complete glyph just by connecting the dots. If you need to undo a certain location with a black dot, you can right+click on top of the target area and it will revert back to empty. Each grid area can hold any of the three states: 1) on or black 2) off or white 3) empty or gray. On state is displayed as black by default. Off state is displayed as white by default. Empty state is displayed as gray by default. Off state or white is relevant most specially if the font is fixed-width as it dictates the distance a glyph will have from left, center or right. Empty state or gray is important for variable-width font as it affects the overall width of the glyph. For variable width fonts, you move the glyph flushed left on the glyph editor window and remove any extra empty grids by decrementing the present column counter located right under the glyph editor window and thereby leaving only the entire glyph all by itself. Below the glyph editor is the glyph tool which contains the following: pen icon for creating glyph itself, move icon to enable the entire glyph move to top, down, left or right from within the glyph editor window. Below the glyph tool are the transform icons which are flip horizontal, flip vertical, rotate counter-clockwise 90°and rotate clockwise 90°. Transform tools are most helpful when copying over existing glyphs and transforming them to form a new glyph. A becomes V, M becomes W, c becomes e, n becomes u, etcetera.

-- The ***middle section*** contains two parts: the upper part which holds the entire glyph content of the font, or lack thereof if you are making a new one. And the lower part which contains ***Metadata*** information such as name, family, weight, slope, presentation size, mean line, baseline, glyph spacing and if the font is either fixed-width or variable-width. You can still further tweak your font parameters via the Metadata section. The ` Fixed width ` toggle located at the right side next to Glyph spacing is of special note. It applies to the entire font file. It does not only apply to a single glyph or group of glyphs. It is the differentiating factor that informs the system if the font is or is not fixed-width. Fixed-width fonts are mostly used for Terminals and for displaying program source codes.

-- The ***right section*** which displays both search input for unicode blocks and the unicode block selection list.
-Metadata and unicode blocks can be turned on or off via ` Menu -> View ` option. Unicode block filters only what to display contained within the range of the block. Basic Latin covers 000-007F, Latin-1 Supplement covers 0080-00FF, Latin Extended-A covers 0100-017F and so on and so forth. Global search for a glyph is affected when a certain block is currently selected. Only by selecting ` Show All ` will the global glyph search work as expected. So make it a habit of confirming that Show All is active before searching for a glyph.

 ### The status bar
 The status bar displays additional information describing what each menu entry and toolbar icon does. It identifies the unicode value of the glyph currently under the cursor. It shows the glyph's visual representation (if available), description and dimensions. The right-most segment displays the code point range of the currently selected Unicode Block. Clicking this segment will toggle the display of the Unicode Block list. Second only to the glyph editor window, the status bar is your next best friend on your path to becoming a font master.
