Applied the follwoing changes:
Updated the Splice* integration tests to test for newly introduced changes to Splice mover
Corrected a problem with arguments passed to find_nearest_res in Splice mover. Before it only looked for nearest res in chain A, now looks in all chains.
I Changed LoopLengthChange mover so it now respects the cut_chain input. meaning: if the input cut_chain is X then it will remain X after llc mover is apllied.
Added source PDB 3UMT to the H3 PSSM database
Added to CutChainMover a functions that finds a chainbreak between input residues
