Support for build configuration DTAP

User had following suggestion:

"

many large companies use DTAP in their software release process (D=Develop, T=Test, A=Accept, P=Prod)

It would be useful if the build settings would support these configurations out of the box and not as now artificial 'debug', 'release' and profile builds which are mostly related to development (debug/profile) or an over simplification of production (just 'release')

In fact DTAP maps to DRP as

D = Debug
T = Debug but called test (used to integrate with other system parts)
A = Release but still a bit test (e.g. certain logging can remain active)
P = Release and optimized, profiled build

Also the build directory should reflect these build types. Unfortunately currently you can choose 'build type' which is just debug or release and there exists no variable to reflect the build configuration
