configs and projectPath

In the last few commits the problem occured
that absolute paths are needed for correct
and unambiguous locations for binary files
or the database.
For the compiler arguments the problem is now
solved with an automatic script, that creates
the absolute paths automatically for different
systems.
The database path is now specified by calling
a new function, that finds the root of the
project followed by a relative path.
