Config file setup

----------------------------

For example: --url poola:porta -u usernamea -p passa --quota "2;poolb:portb" -u usernameb -p passb Will give poola 1/3 of the work and poolb 2/3 of the work. Writing configuration files with quotas is likewise supported. To use the above quotas in a configuration file they would be specified thus: "pools" : [ { "url" : "poola:porta", "user" : "usernamea", "pass" : "passa" }, { "quota" : "2;poolb:portb", "user" : "usernameb", "pass" : "passb" } ]
