[Interest] Qt Quick Compiler

[rpzrpzrpz at gmail.com]

Then that would make the benchmarks that Harri requested a mute point.

Unless you "make clean", the incremental build would not care about
10,000 lines of QML code. It would only "slow" down on the changed QML.

Is there an option to turn off the Quick Compiler for beta builds and
only kick it on during release?
