MEMFIX: ofstreams in ...logger.hpp as static objects were not recognized by MemDebug.

  • now they are allocated via new in the constructor of the ...logger's.
  • Calling new ofstream(..) globally would cause segfaults in some unit tests.
  • Constructor is private (due to logger's being singletons), hence this is safe.

NOTE: the problem is not the static object itself, but what is allocated
dynamically inside the object's constructor (this also concerns previous
fixes)
  • Property mode set to 100644
