Modify JecsTools compat to support partial patching (#470)

Added support for only partially patching elements of JecsTools - specifically, added checks if types that normally would be patched exist. This allows for JecsTools assemblies redistributed in different mods to be safely patched.

Added "JecsLite - Lightsabers" and "JecsLite - A RimWorld of Magic" as supported mods.
