HeadersFooters 0.2.3

A new version of HeadersFooters is out. This one once again tries to bring table prefix compatability. I’ve also converted all my test wikis to use table prefixes, because really there’s no advantage from a testing point of view not to. This particular plugin is still very experimental, so please report any problems (and I’m sure there are many).

bugfix:
* wikis with table prefixes did not update the cache properly, really fixed.

notes:
* I really can’t stress enough how experimental this extension it,
it still needs a lot of testing to work out edge cases, please report them!
* switched to a more permissive and correct bsd-2-clause license agreement for commits

testing:
* releases: 1.17.0
