ResidueTypes: Modifying patch system to allow for multiple aliases per atom
This merge allows one to add multiple atom aliases from a patch file, which previously was only possible from a .params file.
It further adds more aliases to a few sugars, which will help Rosetta load in a few obscure sugars from the PDB that currently fail because of atom naming.
This merge also fixes an error in H-placement on acetyl groups that are not trans.
