FontEditor: Convert to GML and add new edit commands to GlyphEditor

Adds cut, copy, paste and delete to GlyphEditor. Font preview has
moved to a separate resizable ToolWindow. Font metadata can now be
hidden. FontEditor and glyph widgets can now be re-initialized
instead of resetting window's main widget after loading new fonts.
