Changed the GulpFile to use memory instead of temp files for .scss concatenation
Updated the styling for blue and green skins to include dark tooltip border styling
Update the green skin to include a more gradient time stamp progress bar
Merge branch 'master' of https://github.com/CoStarGroup/pro-video-skins

Conflicts:
	css/blue.css
	css/green.css
	gulpfile.js
I don't know how to merge conflicts well. So this is a commit to fix the changes.
