filefield_image 6.x-1.0-beta2

I wanted to wait for more bug fixes or features until I release a new beta, but the situation seems to speak against that, because:
- it seems there are no actual bugs apart from the one that I fixed since beta1 (style options didn't work there, now they do)
- new features are unlikely for the near future because I'm going off to a one-month trip abroad.
- dopry reshuffles filefield again (and imagefield), so the future of filefield_image is unclear at this point.

So, here's a release with style options working. Requires filefield 6.x-1.0-beta2 or -beta3 (which I'll release right afterwards), probably incompatible with subsequent filefield releases (depending on how communication with dopry works out).
