Added uses to command /gh give <player> optional <uses>
Added <optional> uses into the give command both for console and players with gh.admin.
If you have uses enabled in the config.yml when you issue the command
/gh give <player> it will give the player the set amount by default in config.yml.
If you use for example
/gh give <player> 1000 it will give the player 1000 uses. This is
ONLY relevant if it's enabled.
There are no changes in the config. New messages are added by default if missing on server restart.
The crafted grappling hooks will always give the default value in the config.yml
