'info' command, plus lots more changes:

- usage() gets a little smarter; it now knows what function it was called
    from and tries to find a '=for function_name' chunk of data in the script

  - the various list-* functions now work off a dispatcher in Load.pm
  - (...and they all use the new usage() magic to print their helps!)

  - src/gitolite got a lot leaner due to this dispatcher

  - src/gitolite-shell became a lot more easier to read/flow

  - rc acquired '{COMMANDS}', which gitolite-shell now refers to
  - comments in the default rc file changed a bit
  - rc got a new REMOTE_COMMAND_PATT (in place of ADC_CMD_ARGS_PATT)

the rest is perltidy and stuff like that
