file improvements

+ Files: Made listview / gridview switch respect the currently selected
folder when switching views
+ Made the uploader respect the currently selected folder when
refreshing. Now after an upload is complete the view will refresh
the subfolder to which a file has been u ploaded and not always the main
folder.

Removed more file/folder visibility code.

changelog
Arabic Language

Completed and refined Arabic Language files and installation read me
file. Translation approved by sworn translators from iTranslate
Unlimited. Locale used is ar-EG but suitable for all Arabic speaking
populations.
RTL Support

Files to display RTL interface. Modified files only included. All other
template files should be uploaded or change reference to ./standard/*
path. Best practice will be adding auto overrides depending on user's
selected language.
