recola_0.9.4:

1. Fixed the problem with the arguments of the routine compute_process, restoring the momenta as "intent(in)". In process_computation_rcl.f90 added the routine get_momenta_rcl.
2. Implementation of possibility for the user, to select the output-file by using the routine set_output_file_rcl (in the file input_rcl.f90).
3. Minor changes in the computation of wave functions, to improve numerical stability
4. In the on-shell scheme, the masses in the numerator are now real everywhere, also in fermion propagator.
5. Changed convention in colour structures: upper indices are for incoming antiquarks and lower indices for incoming quarks.
6. A minor change in the checks of the phase-space point
7. Corrected the bug in the separation of QED contributions
