happen after release!

Change wrsConfigSource to inform whether dot-config source was local or remote.
Before it contained also information about remote protocol.
Now information from wrsConfigSource, wrsConfigSourceHost and
wrsConfigSourceFilename is stored in wrsConfigSourceUrl.

wrsRestartReasonMonit is moved into place where wrsConfigSourceFilename was
before.
