Now using the compression option on the CodeMirror site to get a single
JS file
This includes codemirror.js file & the 7 mode JS files in 1 file, also
uglify compressed
Result is a saving of around 105k!
Removed the 2 x keymap files and unused files from util dir
These files are all unused, if users want them, they can download
(Same thinking as only including used 'mode' files)
