Add websocket early to avoid KeyError later (#229)

Originally websocket was added to manager.sockets only on a successful
subscription. If that didn't happen for any reason (e.g. most likely
due to an error in bokekjs) then closing a web browser caused KeyError
exception.
Add a sanity check if all websocket connections were closed

Python 3 Support.

This introduces the new dependency `six` and enables Python 3.3 support
for everything but the `bokeh-server` which depends on `gevent-websocket`.
css paths were missing "http://"
using urls which are insensitive to http vs https
Merge pull request #244 from ContinuumIO/bugfix/css_direct_embed

css paths were missing "http://"
running the bokehserver with splitjs False and devjs True does not work.

This is because there is an inconsistency with build/release js paths, and
what is on the server.

I think it is easier to standardize on our bokeh.js living inside build/js, or release/js

This commit
- modifies the Gruntfile to build into build/js and release/js
- modifies setup.py to look for files in that directory
- renames JSROOT to BOKEHJSROOT, since the name JSROOT is a bit misleading, as we have things like css in there
- fixes an os.path.join call which had 'static/js' as an arguemnt, since that's not platform agnostic

This isn't really tested yet, so I would merge this after I get a chance to test it but I wanted to open the PR first.
