This supports the following arguments:
  - detailed (bool) -> G_SIGNAL_DETAILED
  - run (string) ["first", "last", "cleanup"] -> G_SIGNAL_RUN_*
  - no_recurse (bool) -> G_SIGNAL_NO_RECURSE
  - action (bool) -> G_SIGNAL_ACTION
  - no_hooks (bool) -> G_SIGNAL_NO_HOOKS

The default is unchanged (G_SIGNAL_RUN_LAST and nothing else).

Fixes bug 577623.
