Scripts: Add C2PAP to batchelor.

Add the C2PAP system to the available clusters in the batchelor. No actual code
for interacting is there yet, just the decoration. Also fix some minor things
in the executable scripts. They should probably be deleted at some point, as
they were only thought to be for quick and dirty testing.
Add submitJob for C2PAP.

Add the code for the submitJob function for the C2PAP cluster. It is tested and
seems to work. All the other functions which batchelor expects to be there have
been added, but they all only raise an exception ("not implemented") at the
moment.
Add the rest of the functions for C2PAP.

Add all the other functions to the C2PAP submodule. Everything is superficially
tested and seems to work. The functions concerning jobs in error states have
not been implemented (they always return false), because there is no experience
yet with jobs in error states on LoadLeveler.
