jQuery.props should have mapping for "colspan" -> "colSpan"

[dcitron]

Internet Explorer does not accept the attribute "colspan" and instead requires "colSpan" with a capitol 'S'.

A mapping for "colspan" -> "colSpan" should be added to jQuery.props in support.js

Note that jQuery.props already has a mapping for "rowspan" -> "rowSpan", so adding "colspan" there as well seems appropriate.

wrong r number. it's r6351 and r6352, not r6531 and r6532.
