[PATCH] Invalidate /video cache _after_ cutting

[art_k at o2.pl (Artur Skawina)]

When a new recording is started vdr touches the .update file so that all vdrs using the same /video directory rescan the tree and discover the new data. While this makes sense for 'normal' recordings (makes it possible to watch an ongoing recording on another vdr), it also happens when the cutting process is started. This causes all other vdrs to almost immediately reread the /video tree while the disk is busy -- both the cutting process and the clients are significantly slowed down.
This change lets the horde of vdrs loose _after_ the cutting is finished. Edited recordings appear on other vdrs first when they are finished.
