uic: use a real ordered set

Browse Source 
... instead of QMap<Key, bool>. Since Qt doesn't have such
a container, use std::set instead, which also simplifies
some code, in particular, because, unlike the Qt containers,
it does the right thing on attempted duplicate insertion:
nothing.

Saves 6.5KiB in text size (1.1% of total) on optimized
GCC 5.3 Linux AMD64 builds.
