prepare for a release

* Allow unsuccessful replacement of BungeeCord thread pool

Port https://github.com/minecrafter/RedisBungee/pull/76

Some BungeeCord forks have different implementation of thread pool and RedisBungee won't load in such case

* Update RedisBungee.java

 The maintainer of RedisBungee has became inactive, so we have taken the development of the plugin.
 
-RedisBungee bridges [Redis](https://redis.io) and [BungeeCord](https://github.com/SpigotMC/BungeeCord) together.

+## Notice: about older versions of redis than redis 6.0
 
-This is currently deployed on [Govindas Limework!](https://Limework.net) 
+As of now Version 0.6.4 is only supporting redis 6.0 and above!
 
 ## Compiling
