Fix paths for project.py

[0xc0170]

tested with export using mbed (the change, introducing a flag to indicate if we use relative paths or not) and project.py (no regression there as copied flag for progen stays as it was). The fix is the first commit .

The second commit is a cosmetic change , that actually can be breaking for callers of export as I renamed the default argument from relative to sources_relative, as it is more clear what's the intention. I can revert it , just proposing an unification of this flag in the 2 files.

Tested with uvision and IAR (checked the paths are correct ). Using master of project generator (v0.9x should work as there are no changes required for this patch in the progen).

LGTM. A quick scan for relative confirms that the second commit is very likely not a breaking change:
