[API Review] RT-16689: TextInputControl: css "-fx-columns" doesn't work

[Richard Bair]

This issue isn't going to introduce new Class members, but it does affect what is specifiable from CSS and thus requires an API review (although really trivial).

http://javafx-jira.kenai.com/browse/RT-16689

This issue I've hijacked to do more than just add "-fx-pref-column-count" to TextField, but rather to add support for styling a number of properties in both TextField and TextArea.

TextField:
	-fx-pref-column-count: number

TextArea:
	-fx-wrap-text: a boolean value
	-fx-pref-column-count: number
	-fx-pref-row-count: number
