Preparation for ender-based text control 

* added focus listener.  Doesn't do much yet, but when focus notifications start appearing, we'll be ready for them.  The code is in
place to hide selection when we lose focus and paint selection when we get focus.  That's probably not quite right, but it's a start.
We will need to be able to determine the distinction between losing focus to another control within our app, and losing focus to
another app.
* added support for disabled and readonly states in the editor.  This is accomplished by having flags set by the client, and letting the
rules system deal with those flags.  The flags I added are:
     TEXT_EDITOR_FLAG_PLAINTEXT   0x01   // only plain text editing is allowed
     TEXT_EDITOR_FLAG_SINGLELINE  0x02   // enter key and CR-LF handled specially
     TEXT_EDITOR_FLAG_PASSWORD    0x04   // text is not entered into content, only a representative character
     TEXT_EDITOR_FLAG_READONLY    0x08   // editing events are disabled.  Editor may still accept focus.
     TEXT_EDITOR_FLAG_DISALBED    0x10   // all events are disabled (like scrolling).  Editor will not accept focus.
* added WillInsertBreak/DidInsertBreak into text rules, so flags could be checked.  This gets us readonly, disabled, and single line
behavior.
* cleaned up the code that allocates, registers, and destroys event listeners.  Thanks to Kin and Simon for cleaning up the
ownership model on the listeners, it was a big help.
* added support for a max text length.  You can now tell the text editor, be no bigger than n characters.
