Configuring beacon

Beacon uses gcfg (INI-style config files for go structs).

[beacon]
	port			= 8808
	tokensize		= 25
	tokendictionary 	= "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
[redis]
	host			= "localhost:6379"
	password		= ""
[ssl]
	usetls			= true
	servercert		= deps/test.crt
	serverkey		= deps/test.key

The config uses some pretty sane defaults but the following fields are configurable:

• [beacon]
port: the port the API listens on.
  tokensize: the length of authorization string returned from the client
  tokendictionary: the allowed characters that make up the client authentication string

• [redis]
host: this is the ip and port that the redis backend is running on
  password: password to the redis database-

• [ssl]
usessl: boolean (takes true/false) weather or not to use ssl. Defaults to no
  servercert: relative path to ssl cert
  serverkey: relative path to ssl private key
