Otherwise AutoTx will try to process them in each iteration but fail
right away, thus blocking all other transfers while the dir is there.

Megabytes have shown to be a bit clumsy in the configuration files, so
simply switch to the more useful Gigabytes unit.

Fixes #39

"Trace" in the configuration.

Default is "Info", fallback for invalid settings is "Debug".

Fixes #34

Fixes #11

This parameter has a different default setting with RoboCopy in the
Server 2012 version: "DA" (data and attributes), compared to "T"

Forcing this setting to be the same for 2012 and 7 seems to fix the
issue of files not being transferred. More testing is needed though!
