Do square thumb images while preserving ratio (Bug #1397005)

I've taken what aceMa provided in bug report and made it a replacement
for the square thumbs option rather than a new option as we don't need
two square thumb options.

I've tweaked it a bit more and hopefully have got the padding/ratio
stuff more consistent and not using hardcoded numbers so much

And getting it to show descriptions/captions below frame
