New integrity check for minimserver.config file

[goforit]

Found the reason: After restoring all files from a backup DS, I found this data on my DS212j:

root@DiskStation:/volume1/MinimServer/appData# ls -al minimserver.config*
-rw-r--r-- 1 root root 1008 Nov 11 17:07 minimserver.config
-rw-r--r-- 1 root root 0 Nov 5 17:50 minimserver.config.lock

As the date of the lock-file did not correspond to the config one, and its save to delete the minimserver.config itself - then reconstruction to default values happens - I stopped MinimServer, deleted both files, started MinimServer again and voila:

root@DiskStation:/volume1/MinimServer/appData# ls -al minimserver.config*
-rw-r--r-- 1 root root 753 Nov 11 23:07 minimserver.config
-rw-r--r-- 1 root root 0 Nov 11 23:07 minimserver.config.lock

Then I set the contentDir value to /volume1/music with "Properties" in MinimWatch and MinimServer is running well again.
