1. Made this dependent the current version of acs-subsite on HEAD (app group tcl API changes which is also tracked in .LRN, though this dependency is tracked in dotlrn-lorsm, the official way to add SCORM support to a .lrn community).
2. Use the new API and the fact that .lrn now defines a community as an app group to remove calls to dotlrn_community::get_community_id.
3. Removed a bunch of commented-out, .lrn-only permissions twiddling, but left in the toggle inherit call and dotlrn-related parameter/xml extension. This can exist without dotlrn being installed and since there's really not budget available to totally clean this stuff up, I left it in even though I suspect that in practice it's not used.
