Ditch bs-rowlink, make tr hyperlinks full-block clickable in compensation.

Rowlink is nice, but it blocks 'open in new tab' clicks,
which is infuriating. This seems like a reasonable compromise.

Tweak the 'scientific' template tag to show sub-mJy level fluxes as non-zero.

Since we only display to 3 s.f., sub-mJy fluxes (e.g. 0.0005) were displaying
as 0.000. I've also added an extra digit of precision to the float case, to ensure
that we get at least 2.s.f. of information on every displayed value.
Use 'scientific' format tag for fluxes on image detail page.

Fix CSV downloads for runningcatalog_detail, transient_detail.

I just fixed these up to match the html views. Exactly
what context object contains the data seems to vary from view
to view, this could probably use a little reviewing.
(And unit tests, as discussed.)
Remove astropy from requirements - we don't actually use it yet.

Although we might in future, since it replaces pyfits.

Assuming this is the only place where lightcurves are created...

Added units to datapoint labels.
Also, fixed lightcurve y-axis label (jY --> Jy)
