* daemon: Handle new request B_MESSAGE_COMMIT_TRANSACTION. It activates and deactivates given sets of packages. The new packages must be placed in a directory in the administrative directory. The daemon moves them to the packages directory and the deactivated packages to a subdirectory it creates. It also save the old activation state there. * Add private BActivationTransaction, describing an activation change transaction. * BDaemonClient: Add CommitTransaction(), which sends a given BActivationTransaction as a B_MESSAGE_COMMIT_TRANSACTION request to the daemon. Completely untested yet.
