* Minimum SCons version is now 1.0.0

- Code has been changed to reflect this (ie. deprecated functions are not anymore used)
* clean up the C and C++ compiler flags mess.
  - in the environment construction of BlenderLib all the compile flag governing options have been split in the *C*, *CC* and *CXX* containing equivalents.
    C is for C compiler only flags. CC is for C and C++ compiler flags and CXX is for C++ compiler only flags.
    All the platform default config files need to be double checked and fixed wherever it looks necessary. Either DIY, or send me a note with needed changes.
  - a start for the BlenderLib parameter list has been made - all the SConscripts need to be checked and modified to hand in flags properly.
* A theeth request: make -jN settable in the config file.
  - I give you BF_NUMJOBS, which is set to 1 by default. In your user-config.py, set BF_NUMJOBS=4 to have 4 parallel jobs handled. Yay.
