Add ECMPoQmTools module

ecm_create_qm_from_po_files() was actually not very useful in practice.
So that is deprecated, to be removed before ECM 1.0.

Instead, the ECMPoQmTools provides several useful functions:
ecm_create_qm_loader() (which already existed in
ECMCreateQmFromPoFiles), ecm_process_po_files_as_qm() (which has the
same signature as gettext_process_po_files() from the FindGettext
module) and ecm_install_po_files_as_qm(), which is a convenience
function mostly for the benefit of KDE Frameworks (although potentially
useful for whatever other projects have the unusual requirement of a
Gettext translation workflow but no Gettext usage in the code).

NB: some clean-up to the documentation was done by Alex Merry
<alex.merry@kde.org> as part of this commit.
