specify func argument and related cleanup (#183)

* specifies the function argument type in commands.h compared to leaving
  it unspecified. all the functions in cmd_t must have arg_t as it's
  argument.
* changes to commands.h will now trigger a rebuild - this restores old
  behavior prior to 12efa0e
* cg_quit now uses it's argument as exit status
* DestroyNotify invokes cg_quit rather than calling exit directly.
* Explicitly pass EXIT_SUCCESS to cgquit in keybinding
