I just noticed that my editor also did some code cleanup (removing trailing spaces and unifying indentions). I can undo those changes if that is an issue

Thanks for this. Yes, there are a number of unrelated changes that I wouldn't want to pull in (at least not in this pull request - the fix of mixed tabs and spaces I should do myself though - that's messy!), but I think the basic idea is okay. I've never been fully comfortable with the Glyphicon Halflings license and the knock on effect that it has (a link back where available) which is why I've not used it to date. Probably just me being overly touchy about licenses, but I'm still not certain.

I'll probably not pull it in immediately, but play around a bit.

If I do pull it in, can you confirm you are happy with it being under the MIT license?

[mweimerskirch]

No problem, I'll undo the other changes.

As to the license, the version distributed with Bootstrap is licensed under the MIT license: http://glyphicons.com/license/ ("GLYPHICONS Halflings are also a part of Bootstrap from Twitter, and they are released under the same license as Bootstrap.")

I confirm that I agree to the code being released under the MIT license.

Ah - that is good to know! Thanks :-). I misinterpreted the Bootstrap manual in that case. I don't see any reason why I won't pull this in then, but it will likely be in the new year, as I'm packing up for a little holiday at the moment :-)

[mweimerskirch]

There you go. Pull request cleaned.
Have a nice holiday. :-)

Finally getting around to this now - thanks for the PR :-).
