[makefiles/tweak] Allow tweaks to masquerade as bundles if and only if xxx_BUNDLE_RESOURCE_??? is present, defaulting to /Library/Application Support/xxx/xxx.bundle (configurable with xxx_BUNDLE_INSTALL_PATH, xxx_BUNDLE_NAME and xxx_BUNDLE_EXTENSION.)

2013-04-20: Updated for new bundling system.

(I am finally landing this on master: I don't necessarily believe that
it's the best thing to do, but I do think there needs to be some
sort of standard resource storage for tweaks.)

[makefiles/tweak] Don't kill SpringBoard, kill whatever the user says to kill when building the template.
