TPAC: Replace plus / minus signs with text + CSS

[Dan Scott]

While working on bug 956001 I noticed that the plus-sign and minus-sign images, used only for showing more or fewer copies, did not actually do anything when you clicked on them. In addition, they can be reasonably represented as plain text + CSS, saving an extra HTTP request per copy detail page that has more than 10 copies.

Moving the text + CSS into the <A> tag also makes them do something when you click them, which is kind of nice. And, being CSS, it's easy to change the colour scheme to suit a different site.

See branch user/dbs/text_css_plus_minus in working repository.

Removed pullrequest because this isn't quite there. Added another commit, though, to replace the circular rdetail_arrow*.png images in a similar fashion.

I'm finding getting the CSS just right for Chromium / Firefox / etc is annoying though, so maybe somebody else will want to pick this up and polish it off.
