Support for multiple ini files; Parameters temporary workaround
- "parameters" specified via the json workflow test definition may not be interpreted correctly from the seqware command line
- as a workaround, parameters are saved to an ini file which is passed to the seqware command line
- this also required that multiple ini files be supported by the testing framework
- improved logging in Helpers isFileAccessible
Merge pull request #8 from pipedev/PDE-502
