Get rid of the read-only monads (RO)
Move filenames between config files to reflect they belong to server or client

Consequently, writing to the files will be possible only in client or server

Clean up action monads a little bit
Separate target and missile path; move target to StateClient
Bump up thrown weapons now that monsters have more HP

Calculate running direction within the client, not server
Rename location to position
Let targetStrategy be determined by the client
Make hidden doors very rare until AI searching fixed
Let also the actionStrategy be determined by the client
Reninstate the omniscience debug mode
Clean up remebering a level
Undo a wrong part of a sed invocation
