Fix translations files generating

These commits fixes generating *.qm files from *.ts and installing *.qm files. In pull request #2 *.qm files be removed from repo (as it is deducible from *.ts).

Target 'dist' ('make dist' command) may be breaked, but it seems to be broken before. I not know whether used it to make source tarball or builded package. Anyway, if this target has importance, it need to discuss in separate issue/pull-request.
