add missing include directory path in cmake. Thank's to Akihiro Koda for reporting the bug and proposing the fix.

add the option to dump the nonlocal field values for the ASlibs via the programm dump_nonlocal_field.

make PSI bulk MusrRoot files accessible if the file name is generated from the run-number, year, etc.

make sure that git repo info is only added if the musrfit project source is indeed a git repo, and not e.g. a download.

add a full dummy user function class with a global part. This can be used as a starting point to develop new polarization functions. Currently no rge-handling present.
