Building the application menu became to cumbersome so I decided to separate it out into it's own file.  Will use GoldenBear.js for global GoldenBear object and should attach it to the Window similar to the technique used in CodeMirror.

Application menu is still not complete, but many of the placeholders are there.  In the future, a more effecient technique could be devised for adding popup menus such as programming languages, unicode, etc.
