Title: API: Treedropdownfield showsearch default true, provide better ui

* Provide search option to treedropdown fields by default, to provide a fallback solution when trees fail to render (too many children errors)

* Provide better indication/more meaningful styling to search (match chosen styles for consistency)

Tested in Chrome, Firefox, IE8 and IE9
