New minimal Script based on bash.
ts3server.ini is not needed, because its only used when the server get started with the inifile=ts3server.ini parameter.
Also the license aggrement moved to the parameter.
The GET_VERSIONS Grep Command will fail with 1.12.2 but will work with 1.12. Added optional check for 3rd decimal place in the MC Version of Forge and future proofed the forge version for Double Numeric SubMinor version.
Added "\n\ntouch \/mnt\/server\/.ts3server_license_accepted" and changed version number.
I've tested this changes on my installation. Works fine.
Thats my first PR. Hope thats ok so.
