Minor refactor: changed ClientInterface to NetworkInterface in TaskPasser
Merge from dev
Fixed minor bug in test
Made register a bit easier..
Made even easier now
Oops, changed the wrong one
Commented that a Sybil node can just send TASKFAIL messages and interrupt work
AbstractFileMaster now removes its listener when finish or fail
Made new test for byte arrays in DHT
Now it works as expected
Reverted to previous hashcash values
Calibrate hashCash
Test works now
Test works anyway...
Restored javadoc
More output, actucally I think the problem lies when re-pushing
Added toString
Improved ui
Refactoring TaskPasser
