Config file was not read correctly.

Run hexya -c config_file_name not work. Reason: Corbra parses command line args when call Execute() method. How to fix: Modify cmd/hexya.go

1. In func init(), add cobra.OnInitialize(initConfig)
2. Add function

   func initConfig() {
   cfgFile := viper.GetString("ConfigFileName")
   // Read config either from cfgFile or from home directory!
   viper.AddConfigPath("/etc/hexya/")
   viper.AddConfigPath("$HOME/.hexya")
   viper.AddConfigPath(".")
   if cfgFile == "" {
       cfgFile = "hexya"
   }
   viper.SetConfigFile(cfgFile)
   viper.ReadInConfig()
   }

You're right, this wasn't implemented.
