Cutelyst v3.5 relicensed as BSD-3-Clause

Cutelyst the Qt Web framework just got a new license, the more permissive BSD-3-Clause. Back in 2013 when I started the project the LGPL was a perfectly fine license as software on servers can be closed as long they are not AGPL, thus it was permissive enough for the web and REST backends use-cases I had in mind.

Fast-forward almost 10 years and I have used for a few of projects where it was embedded into another application, and I realized that there might be users with commercial Qt license that would like to use it but can't due the current license.

Hesitate no more! It's amazing how much nicer it is to implement client-server applications using HTTP/REST APIs all with Qt/C++, and when real time is needed WebSockets is also there to the rescue.

Since Ubuntu 22.04 has Qt 5.15 and 6.2 releases, for the next releases 5.15.2 will be the new minimum as I want to increase the QStringView usage eventually doing a major version update.

*UPDATE: This release includes a QtWidgets example application showing how to use Cutelyst::Server embedded into a GUI application.
