SpaceFM Release

This script is for use by developers.  It interactively performs a release of 
SpaceFM by increasing the version number, preparing the source dir for 
distribution, commiting the $next branch, merging to $master, signing the 
release tag, pushing $master, starting the next version, and pushing $next.

This script must be run from the git $next branch.

Manual workflow BEFORE continuing:

    backup issues   (optional)
    pull translations from Transifex (tx pull OR tx pull -fl LANG)
    update pot if needed (cd po && ./update-pot && cd .. && tx push -s)
    finalize Changelog
    build and install without warnings (GTK2 and GTK3)
