cleaned up files: updated require sections, removed references to arsdigita and openforce, and replaced out-of-date owner info. Most of these edits were done by hand due to bug 1106; I tried to do the same things the APM would do (remove file sections, etc) and updating the release date to today
changing dotlrn/install.xml to only install dotlrn applets (which cascades to exactly the packages we want for dotlrn) instead of all packages in the file system. Updating dependency info dotlrn package and applet packages info files.
