Config

[andrewclink]

This patch moves $APP_CONFIG into an object at SiriProxy.config. It also creates a new command +genconfig+ that creates the appropriate configuration directory and copies +config.example.y+ into it.

This lays the groundwork for people to use SiriProxy as a daemonized process on *nix with its configuration file in /etc/siriproxy.d, while retaining the original usage pattern of .siriproxy in the home directory.

Based on a quick look at the code, this looks pretty helpful. The configuration file location has been a sort of ongoing issue for a lot of people. Let me take a closer look at it and I'll probably just merge it in.

Thanks!!
