Added 'moai-components' support to Android build.

Support for external/proprietary 'moai-components' was recently added
to the CMake build scripts, seperating public moai code from proprietary
code. Support for this has now been added to the Android build scripts
as well: see the --with-moai-components flag to make-host.sh and
build.sh.
Merge branch 'feature-moai_components_android' into nanocell-development
