Improve jQuery UI Feature Utilization

[null-d3v]

Brief analysis:

• Updated DataTable.ext.classes entries.
• I added a DataTable.ext.classes entry for sFilterInput, adding ui-corner-all.
• I created a new renderer.pageButton entry for jqueryui in the extension file. In this new renderer, page buttons are created as actual jQuery UI Button widgets and not just classed like them.
• I improved some of the stylesheet rules around the paging information and paging buttons. Several DataTables styles were overriding the jQuery UI theme.
• There seems to be no default oLanguage setting for oPaginate.sEllipsis. Currently I have this declared in the integration file.
• Might be several more things that I missed...

Sorry for the delayed reply on this. I meant to look at it in detail today and ran out of time. I will try to do so next week!

[DataTables]

This has been open an embarrassingly long time - sorry! jQuery UI integration in now included DataTables' source repo along with all the other styling integration files.
