libtinyxml: removed recipe and now refer to meta-oe layer

Instead of maintaining a copy of the tinyxml recipe from the meta-oe layer, we
require that the installation also includes the meta-oe layer.
We updated the README accordingly and also updated the description of the
current setup. We also updated and tuned the CONTENT file.

This commit resolves issue #45.
