Stop using Django-provided floatformat template tagrelease_2013-11-30

It turns out this is a HUGE part of our slow mirror status template
rendering, due to the internal workings. Everything is converted to a
Python decimal object which is way slower than just staying in native
floating point. Given we are always dealing with floats when we need to
do our formatting, a home-rolled template tag can accomplish this much
faster.
