[dojox.widget] Add Pager Widget [meta]

[dante]

Upgrade the !dojoc.sandbox.pager.DataPager? to dojox.widget

Initial checkin will be direct port. Code desperately needs a DRY pass, but want to check in "working" code re-namespaced before attempting any optimizations, and to allow for collaboration. Doc / DRY pass coming in incremental parts, and better styling will come courtesy nonken.

All code is originally nikolai onken's [cla] doing.

(In [14452]) testing !strict - removed json data suspecting it is the culprit, which causes test to fail.

refs #7202 - initial checkin of dojox.widget.Pager from dojoc/ with some style cleanups. needs the afformentioned DRY pass, and styles indicitive of each theme (had to remove the dojoc.Rounded widgets from the example). noticing a thing in ie7 where the vertical nodes only occupy the natural height rather than taking a percentage of the page. this widget is marked experimental, and if there was a rating higher than experimental, it would be that. (at least until the DRY run and documentation come about). expect minor API changes.

also tiny style cleanup in RollingList?, and README update for Roller widget.

pager widget is in, though still needs some more cleanups. It works in its current incarnation, so closing this bug for now.
