webhook 2.3.2
- added hook reload on USR1 os signal (i.e. on Linux you can now use kill -USR1 webhookpid to reload hooks from hooks file, useful if you don't want to, or, you've forgot to enable hot reload)
- allow charset declaration in Content-Type header (it will be ignored however, but the correct content type hook handler will be invoked, as opposed to previous versions where nothing would happen)
