Basically it removes compilation-dependency on Python (whole insert.py script has been replaced by a call to dd, so there is no need to have Python installed to build Launcher.dat)
Also, it adds a way to manually specify keyslot on ncchinfo.bin in a backwards-compatible way. I am using this to fiddle with AES engine but could be used on the future if they change the keyslot.
