RTL-LTR support

Actually I've done what's needed for that.
But I'm still in progress..
Here is whta you have to do:
-------------------------------------------------------------------------------------------------
1 - added in lang/* to differentiate rtl from ltr languages.
lang["ltr"] = "rtl" ;
in Arabic language file lang/ar.js and it will be needed for Hebrew too.
lang["ltr"] = "ltr" ;
in all other language files lang/ro.js lang/en.js ...
-------------------------------------------------------------------------------------------------
2 - added in dialog/*.html
document.body.dir = dialogArguments.lang["ltr"];
after:
function setDefaults()
{
to be:
function setDefaults()
{
document.body.dir = dialogArguments.lang["ltr"];
-------------------------------------------------------------------------------------------------
3 - Changed some Arabic translation to make it shorter so it can fit ;P
-------------------------------------------------------------------------------------------------
4 - Changed URL input field ONLY direction to be left to right. (dialog/fck_link.html)
was:
<input style="WIDTH: 100%" type="text" id="txtURL">
to be:
<input style="WIDTH: 100%" type="text" id="txtURL" dir="ltr">
-------------------------------------------------------------------------------------------------


and still working on the rest.
