Add More Languages

# The Overview
Currently BackPacks+ supports [6 languages fully](https://github.com/aj-rom/BackPacksPlus/tree/master/src/main/resources/lang).

I would love to get some community contribution to create a new file within this directory, copying the format as follows.

## Example
Here is the [*en.yml*](https://github.com/aj-rom/BackPacksPlus/blob/master/src/main/resources/lang/en.yml) for reference:
```YAML
# English translation file
General:
Permission: "&cYou do not have permission to use this command!"
CraftPerm: "&cYou do not have permission to craft this backpack!"
NoRenamePerm: "&cYou are not allowed to rename backpacks!"
Use: "&cYou do not have permission to use this backpack!"
Offline-Player: "&e%player% &ccould not be found!!"
Reload: "&8[&cBack&ePacks&b+&8] &aYou have reloaded the plugin!"
BadArgs: "&cIncorrect arguments! &eType &7/bpp help &efor help."
Console: "&8[&cBack&ePacks&b+&8] &cYou must be a player to use this command!"
NotFound: "&e%backpack% &cdoes not exist."
OverLimit: "&7Removed &c%removed% backpacks &7because you are only allowed to carry &e%limit% &7at once."
BackPack:
ItemNotAllowed: "%backpack% &cdoes not let you store &e%item% &cinside."
OnCraft:

OnGive: "&7You have given &e%player% &7- &a%amt%x %backpack%"

## Contributing
To contribute, clone this project or simply just create a new file in the [lang](https://github.com/aj-rom/BackPacksPlus/tree/master/src/main/resources/lang) directory with the associated langauges code. You can find a good list to conform to [here](https://developers.google.com/admin-sdk/directory/v1/languages).
