Fix bug where workers would not execute builtin functions properly.
Bump version to 0.3.7.
Merge branch 'hotfix/0.3.7'

Conflicts:
	CHANGES.md
	rq/version.py
Optionally configure connection as path to Unix socket (tbd: actual connection)
Better placing + testability of socket as a cli parameter
Perform actual connection (+ increase test coverage)
Added a MANIFEST excluding tests from distribution

Otherwise find_packages() sees tests/ as something that must be installed.
Currently installing `rq` creates a `tests` directory in `site-packages`,
conflicting with projects having a local `tests` directory like rq does :)
Ability to get SENTRY_DSN from the environment variables
Merge pull request #192 from brutasse/fix/packaging-tests

Added a MANIFEST excluding tests from distribution
Merge pull request #193 from brutasse/feature/sentry-dsn-env

Ability to get SENTRY_DSN from the environment variables
Remove test cases for the Unix socket config setting.

This is mostly something you would want to test in the redis-py project,
not in RQ.  The test cases make it a bit complex to read them and they
falsely suggest something interesting might be going on in them.
Merge branch 'Plexical-config-socket'
Update CHANGELOG.
Job.create should also accept arguments in list format.
