Fix for selects not working in IE8

angular-ui#158, based on an observed (but maybe not well understood) code change by @careywalker. Basically, just move the ng-click/ng-mouseenter bindings from the LI (choices-row) to the contained DIV (choices-row-inner). So far, I haven't seen an affect on behavior in any browser, but this is with light manual testing.

All automated tests pass with these changes in place:
