fix(searchEnabled): maintain keyboard nagivation

Fix issue where keyboard navigation was disabled when searchEnabled
was set to false.

Caused by hiding the input box which prevent key events from
propagating to the directive.

Resolved hiding the input offscreen when searchEnabled is false.

Fixes angular-ui#1059, fixes angular-ui#917, fixes angular-ui#589, fixes angular-ui#375
Closes angular-ui#1543, closes angular-ui#1114, closes angular-ui#1109 (supersedes all)
