* It seems due to deficiencies in Qt's design, there will be a
substantial need for these small custom subclasses just to add basic
functionality that should have been present in the original. So we'll
adopt a naming scheme of QFooBar -> RDFooBar for this 'almost the
same widget' type subclassing, compared to more custom/changed ones.
* Suggest users to use VS on Windows
* Add a top-level wrapper Makefile and disallow in-source builds
* Support clang
* Centralize compiler flags
* Remove all occurrences of "if(WIN32)..."
* Make qrenderdoc an external project
* When I went to explain to someone why the target was named Profile and
not Debug as you might expect, I realised the reasons were entirely
opaque and historical. So instead, rename it to Development since that
is really what it's for - any profiling would be done in Release mode.
* Building qrenderdoc on windows will be supported just because that's
likely where I will be developing it mostly, but for the foreseeable
future it won't be built by default. If it ever gets good enough to
replace the .NET UI, then we can look at it again.
