Allow bundling translations as resources by setting `BUILTIN_TRANSLATIONS`.
This is useful to create self-contained executables.
The code for this is already in qtutilities so we basically just need to
look within the resource root `:/` for translations as well and tweak the
build script a little.
With this change it is still possible to load translations separately from
the usual locations as it is only effective if `BUILTIN_TRANSLATIONS` is
set to a truthy value.
* Prepare use of qtutilities for improving UI
* Remove code for enabling warnings that has been copied from c++utilities
* Remove code for various details now handled in qtutilities helpers
* Simplify configuration of executable
* Simplify finding Qt modules
Removed video options now defaulting to none.
Changed USE_FLUIDSYNTH to EXPERIMENTAL_USE_FLUIDSYNTH as this option is not working yet
Fixed a problem that prevented a midi keyboard connection from working.
moved the colour coded notes to the preferences dialogue.
cmake with no options now works correctly.
