Add core, UI and feature plugins for the new autotools project which
uses template wizard and core build.

project as described using a template manifest.
The project generator sets new autotools nature associated with new
autotools build config provider.
The generated autotools project has been tested to compile fine with gcc
(x86_64-linux-gnu-gcc) toolchain.
