Need to add a simple method of adding custom templatetags

Perhaps from /etc/cmt/templates

We can add custom library locations with the following directive in the settings.py for TEMPLATES:

OPTIONS={
    'libraries': {
        'myapp_tags': 'path.to.myapp.tags',
        'admin.urls': 'django.contrib.admin.templatetags.admin_urls',
    },
}

added enhancement label

changed milestone to %Release 2.6.0
