Merge pull request #465 from am11/master

Settings: Fixes XPath condition in Settings
LESS: Removed extra new lines. Fixed #447

This removed the extra new lines in the output CSS file. The use of this
feature was to make preview window look better, but it ended up messing
with the source map and WE2012 compatibility.
Test: Removed unneeded regex from LESS testhelper
CSS: Added status messages. Fixed #188
