Room page's interface tab is blank in NAV 4.4.0

[Morten Brekkevold]

The room page's "Netbox interfaces" tab is always blank under NAV 4.44.0.

Using the developer console, it is apparent that the backend URL that is queried to get tab contents fails with a 500 error. The following traceback is reported:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xa0' in position 0: ordinal not in range(128)

This appears to be due to a maladaption to various Django versions in the nav.django.templatetags.info.days_since() function. It was committed at the same time as the time_since() function. The latter uses a unicode string format, the former does not. Under Django versions >= 1.6, this ultimately fails, since the value retrieved by the get_stupid_space() function is not ASCII-encodeable under Django >= 1.6.

This whole adaptation and the "get_stupid_space()" function should be wholly removed. It is useless as long as we have a specific requirement of django 1.7.

Also, the page is not *always* blank. If no ports on the page are active "now", the error will not be triggered.
