A new version for this quarter and to celebrate Dotclear's 21st birthday!

A major overhaul of the code, which will continue for several more versions, but which will not call into question the current ecosystem — no incompatibilities to be expected, apart from those already known — of plugins and themes.

The backend has been slightly revised to make it more coherent and unified, and this is also in progress at the same time as the code is being reworked.

A few bugs fixed.

In short, it's still moving and it's going to be fine!
