3.6.0 -> Language presets & Hotbar selection syncing

This update brings 2 new requested features:

1. Language presets. We thrown out a single message.yml file and moved all translations to the lang/ folder.
Pre translated languages are: German (de-de), English (en-us), Chinese (zh-cn)
Thanks again to xucy for providing the Chinese translation and the idea

2. Another requested feature by our own private server community was another sync module: Hotbar selection syncing
It is now possible by enabling the sync.selected_hotbar_slot to sync the Selected Hotbar slot. It makes much sense to use this
in combination with the inventory sync module, making player's live easier.

Again due to the CraftCore migration mysql bugs occured. This time with older versions. Make sure to use the newest version of this plugin (3.5.4) or visit the repository directly ( https://github.com/Lostes-Burger/MySqlPlayerBridge)

I am really sorry for the Update yesterday.
I made an mistake in the migration to CraftCore lib resulting in a MySql condition error.

Thanks to Hyworld for bringing a few bugs to my attention, the main one caused by the NBT-Api plugin download feature, after some thinking I've removed it completly. The NBT-Api plugin needs to be downloaded manually now.

- All player kicks are now async
- Player data dump files are now using "-" instead of ":" for timestamps to ensure windows compatibility
