Use conanfile.txt instead of conanfile.py

The .py file was useful mainly for Conan 1, where the .txt file lacked
features to control test and tool requirements and where the files are
generated. With the "layout.cmake_layout" setting the files are output
to "build/generators" instead of the current "conan" directory.

Fixes #109
