two scripts that make local app building by hand quite a bit more pleasant

one will download all your forms in an app to a directory structure
based on the module configuration.

the other takes forms in that directory tree, reuploads them, then saves
(and optionally releases and stars) an application.

works great for fast iteration on a phone

added django compressor related things to apps, requirements and localsettings
compress css on base.html, add stylesheets block

the logged out template is never actually used, so remove it altogether (it's confusing compressor)
