LPS-21488

Brian- I changed the patching format since we don't build Shindig from source. Instead, I modeled the format after how we patch application servers (portal/tools/servers/glassfish/patches). shindig.war is now the original unmodified war and the jars will be updated during the merge task. I created subfolders per modified jar instead of per LPS-XXXXX to make it obvious during development when two patches modify the same class (Shindig will need to be compiled with both patches). I also included the diff for each patch in the file LPS-XXXXX.patch. lmk if I should change anything.
