The latter one is an action that potentially takes a long time as all
directories have to be searched recursively there, so rather do not do
it unless really necessary. As free space checks are done by the service
during its main loop but grace location checks only at specific events
forcefully combining them could have a strong negative impact on service
performance.

This introduces a new optional configuration parameter called
"LogLevelMonitoring" to adjust the log level of those messages related
to the load monitoring of the service.

Fixes #50

This prevents at least the log file from being cluttered up completely
in "normal" operation. As stated in #50 the level for those messages
should be configurable to allow for easy adjustments without the need to
recompile the service itself.

Fixes #38

Since we're now back on using a central location for storing temporary
transfer files, it does make sense again to check for that location to
exist on service startup (refers to #16).

This reverts commit 10640754.

The name reflects the functionality much better.
