New Features:
- in the reload command added in a check to see if you have inputed to few or to many arguments
- in the reload command added in a check to make sure you are inputing a valid argument
- in the reload command added in tab completion so you can see what arguments are valid
- you can now change the green, yellow, and red ping colors in the config.yml

Changes:
- Handled the register of the reload command appropriately in the main class
- Renamed file names to follow the general rules of naming
- Renamed 'tablist-ping-update-delay' to 'update-delay' in config.yml
- Renamed 'ping-brackets-left' to 'brackets-left' in config.yml
- Renamed 'ping-brackets-right' to 'brackets-right' in config.yml
- Allowed 'ping-position' to ignore case sensitive when set to 'front' or 'behind'
- Instead of throwing a runtime exception when 'ping-position' is not set to 'front' or 'behind' it now gives off an error message (this would reduce console spamming)
- reload command is now: /pingtl reload
- reorganized the config.yml comments and rewrite all comments
- Set a default value for 'show-ping-brackets' if no value is set
- Set a default value for 'show-display-name' if no value is set
- Set a default value for 'green-ping-max' if no value is set
- Set a default value for 'yellow-ping-max' if no value is set
- Set a default value for 'update-delay' if no value is set


** NOTE: when updating to this version backup your values, and delete the old config.yml file; config.yml has gone though changes which a new config.yml needs to be generated **
