This plugin mostly sets up a "Text editor>" submenu, that allows browsing files, creating a new file, and managing a history of previously opened file for easier re-opening. It restore previous scroll and cursor positions on re-opening. Additional "Check lua" syntax button is added when editing a .lua file, and prevent saving if errors. The text editing is mainly provided by the enhanced InputDialog. InputDialog: added a few more options, the main one being 'save_callback', which will add a Save and Close buttons and manage saving/discarding/exiting. If "fullscreen" and "add_nav_bar", will add a show/hide keyboard button to it. Moved the preset buttons setup code in their own InputDialog methods for clarity of the main init code. Buttons are now enabled/disabled depending on context for feedback (eg: Save is disabled as long as text has not been modified). Added util.checkLuaSyntax(lua_string), might be useful elsewhere.
