Preferences.m

Author: Ali Ozer
Preferences controller, subclass of NSWindowController. Since the switch to a bindings-based preferences interface, the class has become a lot simpler; its only duties now are to manage the user fonts for rich and plain text documents, translate HTML saving options from backwards-compatible defaults values into pop-up menu item tags, and revert everything to the initial defaults if the user so chooses.
The Preferences instance also acts as a delegate for the window, in order to validate edits before it closes, and for the two text fields bound to the window size in characters, so that invalid entries trigger a reset to a field's previous value.
