Can we please get a `--set-preprocessor-definitions` argument for the Projucer.

I’m writing a build script for my projects and want to be able to specify things like `TRIAL_MODE=1` without the need to do it manually.

+1 this would be very useful, does anyone know if there is a way to do something like this with currently msbuild and xcodebuild?
