this lets us know the arguments of commands that fail
Add timestamp to URLs in debug mode.

Adds a URL parameter with a timestamp to the end of individual
JS and CSS URLs when set to debug mode. This is to avoid caching
in certain cases when developing locally, such as working on a 
test Facebook app.

Also fixes the tests to handle this change and adds media files
to the test settings that were previously empty so that the tests
actually test the right output (previously they were comparing two
empty strings due to the empty minify bundles).
allow for http/https urls to render without media prefix
do not block on HTTP errors when fetching external JS/CSS
Fix hard-coded MEDIA stuff

Django 1.4 uses STATIC/STATIC_URL for static assets and MEDIA/MEDIA_URL
for uploaded files and things like that.

This adds an additional setting which switches jingo-minify to use the
STATIC settings. Doing it this way maintains backwards compatibility
with existing Django sites using jingo-minify, but lets new Django 1.4
based sites use it and have things in the right place.
Use Django's static finder if appropriate.

When DEBUG is true and the new USE_STATIC setting is set, let Django see
if it can find the static file. This allows files to be found that are
in 'project/app/static', instead of only the centralized static
directory.

This change really only effects development, but it prevents having to
run './manage.py collecstatic' after every change while in development.
Instead files static files will be updated as they are changed so edit,
save, refresh works.
Update CONTRIBUTORS.

Remove unused import from fabfile.
Use mtime for build ID in dev for debugging.

Using time.time() for a build ID in dev breaks Firefox's script debugger
(see in particular bug 783393). This replaces time.time() with a helper
that returns time.time() for remote scripts and the file's mtime for
local scripts.
