fix addtional styles, they got lost somehow
use union instead of or: add massive performance improvement when clearing view cache under special circumstances

speeds up clearing view cache by a factor of 50 when:
- many view cache entries (300k+)
- many ors (1k+) because deleting cache recursively

Reason is that this crappy mysql does a full table scan when using ORs, but doesn't when doing the same with UNION SELECT
