Configure OFT via config file

[kaklakariada]

Is your feature request related to a problem? Please describe.
Sometimes the default settings of OFT don't fit your project.

Describe the solution you'd like
To allow overriding the standard settings of OFT per project we will introduce a project central configuration file that takes precedence over the built-in configuration of OFT. Command line options always win.

Describe alternatives you've considered
Specifying command line options for every call is inconvenient. We also considered external property files but these also require at least one command line options.

Additional context
For an example why this is useful please check #352.

I suggest using Java properties for this purpose. It's a simple and non-invasive solution.
