Time-dependent tag cloud generation

[dkriesel]

I think it would be nice to give the tag cloud an option that makes it generate itself out of, say, the blog entries that were posted in the last year. I don't request some complex time generation rules, but for example the opportunity to set a cut-off date or a relative period of time (e.g. 1 year or 3 months) would be great. Anyway, thanks for the great work!
