userportal,webadmin: Unable to scroll down template list using IE9

Three issues:
1: when clicking the scrollbar next to the template selection, IE9 did not fire
 a click event properly (a known IE9 bug). Fixed by attaching the listeners to
 the parent element (the whole suggestion box).

2: when using up/down keys, the proper template has been selected, but the view
 was not scrolled into it. Fixed by scrolling into the view after pressing
 arrow keys and also when opening the suggestions.

3: tweaked the CSS a bit so the content of the suggestions are not shifted

Tested on IE9 and FF.
