QB64 Phoenix Edition v3.4.0 Released!

[DSMan195276]

I created #234 on GitHub for the

_DESKTOPHEIGHT

and

_DESKTOPWIDTH

issues on Linux, it needs some investigation but I think I get the general idea of the problem.

Additionally we're working on various fixes to the tinyfiledialogs library (which underpins the new dialog support), that will likely be out in the next release.
