refs #4133 - serious style and code changes to _Picker and TimeTextBox. 
intriuces ie6 regression regarding popup width and offsetWidth ... but is in much better working state.

adds testcase for TimeTextBox, too. no tundra styling. all work is being done in dijit.css atm - defer to dijit experts on how to break out styling, and still
needs more tundra-eqsue styling some.
