People overlooked the lock icon and then asked how they could collapse
the file manager
By having the lock within the display area it should bring more
visibility to it
Everything related to the file tree display, icons etc moved to it's own
file
This is so we can use this CSS file too, without having an additional
CSS reset and body applied
Main reason for doing this is so we can show icons from editor.php
PNG image now has 2nd state for open dirs
.refresh class is now fixed position to always be visible
UL has margin-left set also to resolve CSS issues
New dirOpen:before pseudo class to show open dir icon
All other icon X position refs moved along 16px
All filetypes now show icons via single sprite sheet
This works via setting a class with pseudo :before containing icon sized
block with icon in BG
blank.gif is used as a sizing placeholder for LI images
Removed a few trailing semi colons
Hex codes shortened if poss (ie, #888888 becomes #888 and #ff0000
becomes #f00)
Swapped text colour on tabs, selected now has black text, others white
text
Global variables removed from JS file
Plugins system evolved, now including setInterval
Seperate CodeMirror instances per tab
backupOpenFiles plugin created
Minor fixes & improvements
