Dump filenames without spaces about django-smuggler

[jaap3]

The datetime part of the filename is appended here:

django-smuggler/smuggler/views.py

Lines 38 to 39 in 695699d

	filename = '%s.%s' % (datetime.now().isoformat(),
	settings.SMUGGLER_FORMAT)

, a patch that replaces the colon with an empty string will probably be accepted.

The app-model bit before the timestamp probably comes from here:

django-smuggler/smuggler/views.py

Lines 86 to 87 in 695699d

	return dump_to_response(request, '%s.%s' % (app_label, model_label),
	[], '-'.join((app_label, model_label)))

, I'm not sure how the extra dash ends up there. If you can find out why, a patch that fixes is will be appreciated.
