Minify js files with django compressor
Adapt navbar to look how it used to
Make faceting on document work with less

Change things around too
Handle js with django-compress better

No preprocessing (duh), just minifying in production with slimit python
package. Also, core css & js are bundled separately from page-specific
stuff so that they don't need to be repackaged with every request (duh)
Merge branch 'minify-js' into django-compressor
Don't use bootstrap sprites
Bundle common admin js, use non-minified wysihtml5

Trying to minify the already minified wysihtml5 file was creating
errors.
Fix broken "dialog" js
