re-scan directories more often

Reported by [email protected], Mar 4, 2012 Movist seems to re-scan directories when you select the directory. However, if you play a movie, finish, and then it returns back to the directory listing, that directory is not re-scanned. So if new files have shown up there in the meantime, you have to go up a level and then back down to see the new files. Directories should be re-scanned each time they are displayed, instead of just each time they are manually selected.

Ugh, I thought I was posting it in the issue tracker in my repository - forgot that forks don't have issue trackers. I was considering migrating issues that are stale on google code.

By all means, migrate anything you feel should be addressed. This particular issue bites me a lot.
