New fileName var
CodeMirror lib used to allow folding of code on clicking gutter
HTML folds on <tags> and JS & PHP fold on {braces}
+ in gutter indicates folded area
Code assist now won't add an end tag if yours starts with a / (ie, it's already an end tag)
Also won't add an end tag if yours starts with ? (ie, it's ending a PHP block: ?>)
Switched from using the htmlTagArray to determin an end tag, to the tagString var
CodeMirror 2.23 handles tabs in a different way, so extraKeys has been set up to handle differently to new default
Old code removed related to showing results on clicking (now handled onChange as that's more efficient)
2 x JS scripts loaded from Code Mirrors lib plus the call to allow selected text matching
Different styling for visible & hidden classes
These classes mean not only faster tab switching but also fixes render problems on some computers
No longer creates 10 x instances
Instead creates CM objects (& cMActiveLine) on demand
All hardcoded refs from 1-10 removed, now dynamic
Additional code to stop it seeing just loaded files as changed
li tags are now also inline
ActiveLine CSS class added, shows this on cursor activity
Improvement to avoid doing this out on highlighting of text
Will no longer append end tags if in a JS or CSS file
a tags are also now appended inline, no line returns
Global variables removed from JS file
Plugins system evolved, now including setInterval
Seperate CodeMirror instances per tab
backupOpenFiles plugin created
Minor fixes & improvements
