```
Product renamed to match the name used on the Product website and inside
the update.xml used by the update script.
This also updated the version to 173.3727.79.
Previously, we used symlinks to create short name aliases. Symlink
basenames are used as argv[0], and consequently as WM_CLASS hint
when executed. This confused desktop managers, which use the hint
to pair desktop files with running applications.
This patches uses exec scripts instead of symlinks just like the
official deb package does, preserving the sublime_text prgname.
