Based off work from @hyperair that was merged at some point in #677, but reverted since then (see there). This adds a couple bits on top to fix some issues, and I believe the "meh no GTK2" whining of mine is lost to time and the fact there's no supported webkit for GTK2 anymore anyway.

BEWARE: this has been given little testing in the 2020s, I just rebased, merged a couple branches to the point there diffed empty, and did some very basic testing (it builds, it runs, and *seems* to work). Take it, leave it, improve it, comment on it, etc. I'll be there try not to forget looking at this for any comment though :wink:

NOTE: it's not at 100% feature-parity with the old version, mostly because of API changes regarding the inspector (II[RU]C, docking settings are not as controllable anymore), yet the inspector itself has seen countless improvements of course. But again, maybe things have changed since 2018.
