fix(django-rq/templates): updated job.status to job.get_status

When using the django_rq.urls, a depreciation warning is thrown because job.status is depreciated in python-rq. This prevents you from viewing the jobs entirely. The templates have been updated accordingly

feat(setup): updated install_requires rq to 0.4.6

job.get_status was depereciated at the 0.4.6 release, at this commit https://github.com/nvie/rq/commit/f5c3c9a6ddd226ecd56a528895f4d9c9a2bd98f7
