FileManager: Deny rename in PropertiesDialog if user can't write in path

The FileManager PropertiesDialog always let the user change the name of
files and folders to then be prompted with  write permissions error.

Now it checks for write permissions on the containing folder so it can
"disable" the TextBox input. We can't really disable TextBox right now,
hence the quotes.
