Clicking on scrollbar to scroll content set the mouseDown state to true
This wasn't being reset on mouse up and moving mouse pointer towards the
edge of the file manager enabled resizing of width
Now on going beyond editor width (-scrollbar of 20px), sets mouseDown to
false
When redoing changedContent values, no longer consider if these keys are
being pressed:
Escape (27), Caps Lock (20), Shift, CTRL, Alt, Pause/Break (16-19),
Left, Up, Right, Down (37-40), Num Lock, Scroll Lock (144-145), Insert,
Delete (45,46) <<-- mistake, Page Up, Page Down, End, Home (33-36), Left
Win Key, Right Win Key (91-92), F1-F12 (112-123)
This is because CM's changed event will not be triggered with these keys
and I'm not calling onkeypress anymore
Also, rather than now just setting and ending up being stuck at 1 (ie,
changed), we're now detecting if we have at least 1 undo level, if so
set to 1, otherwise 0
(This means you can make changes and undo back to the start and it
doesn't count as a change)
Because this is being handled on changedContent array, no longer need to
consider undo level size when figuring out close button BG colour
openFileMDTs were not being shuffled along when closing tabs but are now
Fixed issue with string replacing closeTabButtonX() - brackets not
needed
theme, tabsIndent, openLastFiles, tabWidth, previousFiles, showFileMenu
& foldStyle all now contained within ICEcoder object
showFileMenu is a function to ensure file manager menu continues to show
The few instances of i now have scope
Initing the var fileName
This is to reduce the number of global vars
The only global vars should now be ICEcoder, docRoot & iceRoot
