Minor server template cleanup
Merge remote-tracking branch 'origin/master' into server-styles
Rename base templates (use underscore to indicate private)
Add bokeh/server/templates/_base.html super template
Add server bootstrap 3.1.1
Fix .gitignore in bokeh/server/static
Include bootstrap in server base template
Add jquery to server/static to make bootstrap happy
Restore {{ self.script() }} in _page_base.html
Use server's bootstrap in src/coffee/server/usercontext

This code should really belong to a different (server) build,
to make sure we don't confuse what styles should go where.
Move jQuery.noConflict() to src/coffee/main.coffee
Use server's jquery (window.$) in src/coffee/server/usercontext
Use data-toggle to restore accordion on main server page

We shouldn't use data- attributes for enabling JavaScript
features, but $(...).collapse() doesn't work right now.
