Additions to logging capabilites in an attempt to debug problems where calling QLibrary::load somehow causes the program to reload LogOutputPolicy which has the effect that access to the logfile is lost and logging stops prematurely.

Rework of HelperMacros.cmake to 1) fix problems with missing library paths in the RPATH of executables and 2) render the script output more informative

Change to default behaviour w.r.t paths handed over to OpenPass: When relative folder paths are passed for arguments "--lib", "--results" and "--config", the current working directory is now used as the reference/root directory of said relative paths instead of the folder where OpenPassSlave is situated in. The corresponding unittest is adapted to reflect that change.

VehicleModels: Importer now asserts that maxDeceleration is a positive value. Also added "maxAcceleration" property to the corresponding xml-files so import can succeed.

Compiling on Linux: Added 'troubleshooting' section and explained fix to problem where dynamically linked libraries where not found at runtime, causing the program to fail

fixed print to log file, write went out of scope in MSVC, thus a capture by value was required (took me a while to figure out)
