* The GUIInvoke object takes a QObject, and uses QPointer to check that
it hasn't been deleted when the callback fires. This prevents delayed
callbacks from executing after the object has been deleted and
crashing.
* In most cases the pointer is just 'this'.
* Initially add support for spirv-cross and spirv-dis.
* When possible we'll auto-detect the tools in path or in the build's
plugins folder. Otherwise the user can add it and add their
executable path.
* We still use the first disassembler for editing - in future it would
be good to allow selecting the disassembler at edit time (as well
as allowing multiple compilers).
* The main addition here apart from some extra stubs is a new rdc type
for date time objects.
* Although the module doesn't do anything and is only used for docs
reflection it is desirable to not have to link against Qt as this
can cause problems when linking the module without unresolved symbols.
