Merge pull request #13 from dmedov/dev_linux

Added frok config file (/etc/frok/frok.conf) parsing. If file doesn't not exist - it will be automatically created (with all required folders).
If some of mandatory parameters are not specified - their defaults will be automatically written to the config file.
So if you want to create config file - just run FrokAgentApp with valid parameters, defaults will be written to it.
