changes to custom command invocation etc.; see below

- 'post-compile' subdir moved under 'commands/' but only for
    sanity; has no real significance now

  - new, internal use only, gitolite command run-all, as in

        gitolite run-all POST_COMPILE

    which runs all the commands in @{ $rc{POST_COMPILE} } in sequence.
    You can sdo this for any section of course, though this is the only
    one in the rc right now.

    (Future candidates: PRE_GIT, POST_GIT, PRE_CREATE, POST_CREATE)
