Misc.less issue fix

Fix for the issue #242.

I am not able to recall the reason why those styles were left there in misc.less. But most likely they are leftovers from over JQuery UI-bootstrap2 misc.less files.

On a side-note, I also am seeing that since my last commit about 6 months ago .. there has been few changes to the css version of the file and hence LESSd version and CSS version do not match anymore. While the differences are small.. there are quite a few occurrences of such differences. I will review the less version in coming days to make it matching with the CSS version.
