Title: Updated Glyphicons to use v1.6, as well as added a 'grey' coloured set of glyphicons

Updated the glyphicons set to use v1.6, and added a variable to the LESS sheets.

Also added a 'grey', shadowed version of the glyphicons (as well as normal and white), and added an example of it to the docs.

Fixed a small typo in variables.css (which is why the previous pull request was cancelled).

From the Glyphicons changelog to v1.6:
