Changeset 8569 for code/branches/unity_build

Message:

Changed binary CMake option DISABLE_BUILD_UNITS to string option ENABLE_BUILD_UNITS with the following possible values:
off/false: Turn off completely
partial: Only combine files explicitly specified with BUILD_UNIT
full##: Use ## source files per orxonox library and use manual build units

for external dependencies. Example: full8 will in general use 8
source files per library, but more specifically tries to occupy
8 CPU threads.
