Building object directory is computed by using path to source given in .pake file

[Quasek]

This causes a problem when a path to source is not under a directory where .pake file is located.

This apply to either relative path (../../../../source.cpp) and to absolut path ("C:/Sources/source.cpp").

When such source appears then object file is not built at all (regarding absolute path on windows) or is built not in __build directory (regarging relative paths like ../../../../).
