NimManager: try to allow 64 sat positions

As actually with Diseqc you can assign 64 LNBs, why not using this

UNICABLE users need to reconfigure their settings.

Screensaver: change to a screensaver that ask less resources
Revert "Add screensaver to MovieSelection for playing MP3s"

As it seems here to break the EOF detection of MP3s, I still do not have a
good clarification why

This reverts commit d30a83d75128263d77a4aab5134e9bd3e4470bda.
