Changes:

[PJ Fanning] gradle wrapper license details

[PJ Fanning] gradle wrapper license details

[PJ Fanning] update Java 11/17 FAQ entry

[PJ Fanning] remove license items relating to bundling jars - no longer needed 
since we don't bundle these jars any more

[PJ Fanning] provide more info in license about inbot-utils

[Dominik Stadler] List some recent changes

[Dominik Stadler] Mention to look for existing bugs before reporting a new one.

[Dominik Stadler] Add FAQ entry for thread-locals and how to clear them

[Dominik Stadler] Bug 66521: Add a utility to clear all thread locals

Otherwise some applications may complain about left-over things,
e.g. Tomcat sometimes reports warning logs if Threads are not
cleaned up before being passed back into the global thread-pool.
