Updated issues list

Hi all,

Please have a look at

http://www.w3.org/International/its/itstagset/issues

I have deleted the category "ongoing", which is now part of "Actions for
the Working Group or single participants". The list also contains a
postponed item, see http://www.w3.org/Bugs/Public/show_bug.cgi?id=3126 .
If there is s.t. else you want to have for a possible future ITS
version: Please enter a bug in bugzilla.

Felix
