Upgrade CodeMirror and other deps
Big upgrade to CodeMirror but I seem to have got it working. Upgraded other deps that were a bit old, including Brucedown which now has a newer pygmentize (including Swift syntax highlighting support ... yay?).
Published to npm under the tag 'dev' as 3.0.0-pre01. Would appreciate others giving this a try before we release a new version.
For some README.md I have problems opening. morkdown hangs and in the bottom left corner I get Waiting for localhost...
I also get ATTENTION: default value of option force_s3tc_enable overridden by environment., but I don't think that is related, since I get that even for some READMEs that can be opened.
Try with this file https://github.com/micnews/sshout/blob/master/README.md if you want to reproduce.
Thanks @ralphtheninja, another bug in brucedown which has had to change somewhat now that marked does async. This particular one was triggered for the case where there's syntax highlighting but no "lang". Fixed there and upgraded the dep here, published as 3.0.0-pre02.
Works! :)
