a few quite big fixes.

1 trap fortran stops on major compilers.
   so ipython won't crash when you do pycamb.camb(10). ifort and gfortran shall be both traped.

2 properly install / locate the template file
    for non lensed CL(what does it do anyways?)
    previously that file has to be in current directory. now you don't have to worry about it at all. It is copied to the package directory and the path is set in __init__.py . A new function is added to the generated f90 wrapper.
