This switches all our unit tests to use the new jasmine.suites utility

library. It breaks down all the '/'-separated paths for each file's test

namespace into test suites and combines them to make it easier to suites

spread out across files.
All existing suites are placed under a 'djblets/' namespace, which will make

it easier to distinguish Djblets tests from other modules.

Ran the RB test suite and saw that all Djblets tests were categorized under

a 'djblets' suite. I was able to run that and the nested 'configForms' suite,

and saw all tests within run.
