ArangoDB 2.5.1

[Ingo Friepoertner]

New release ArangoDB 2.5.1 comes with new features and several bugfixes. 

Here just the main additions:

• ArangoDB has an Http interface for retrieving the lists of currently executing AQL queries and the list of slow AQL queries.
• Running AQL queries can also be killed on the server. 
• added option --database.ignore-logfile-errors to control how collection datafiles with a CRC mismatch are treated.
