- Added flags for services and service permissions for peers

Flags are identity-related, meaning that all locations of the same peers have the same flags.
- It's now possible to tweak which services each peer can use. Service that can be disabled are
  forums/channels, discovery, anonymous routing.
- by default, peers have all flags on.
- fixed missing error msg in p3cfgmgr when serialisation fails.
- fixed bug in RemoteDirModel causing infinite loop to happen when group name is unknown
