Only last plugin commands are executed

[Kloadut]

I noticed that only alphabeticaly-last plugin commands can be executed, even if all of them are displayed on "help".

For example, with a fresh install of dokku:

$ pluginhook commands help
    logs <app>      Show the last logs for an application
    url <app>       Show the URL for an application
$  pluginhook commands url myapp  # Nginx plugin
    http://myapp.mydomain.com
$ pluginhook commands logs myapp  # 00_dokku-standard plugin
$ (no output)

By extension dokku logs myapp does not work on dokku ;)

Hello, just some comments about this issue:

1. the description doesn't feel right: as far as I tested: all hooks are called (not just the last one), but only the last hook will print anything to stdout.

2. it's real and it may surprise you if you are not told.

3. it seems it's not an implementation bug but this is by design: a hook get its stdout piped to the stdin of the next hook:
   https://github.com/progrium/pluginhook/blob/master/pluginhook.go#L43

4. would there be a way from within the hook to escape this behavior? I see people putting a cat at the end of their hook. That may work but eventually you want to log at real time. Any other work around would be appreciated.
