+ RemoteUpdateState triggers file download
+ New RecoverState and handleRecoverEvent added
+ static method to construct recovery file name from original filename
and version number
+ Stubs for recovery handling
! The recovery does not work atm, since Peerbox must be adjusted to the
new H2H version
Adjusted ClientNode to new H2H version
Added further test utils for recovery tests
Update: Write smaller files to see difference on first glance
Move: Wait for all files to exist, not just the last one (bug)
Recover: New class for file recovery tests
ActionExecutor: Commented error code switch to deactivate errorhandling
based on code, as atm. many errors from h2h occur which have to be
solved first

Action/UserManager: small changes
PeerboxFileAgent to conform with H2H API, classes for recovery
