[scribus-dev] Scribus 1.5.1svn AppImage

[probono]

Working on delta updates for AppImages which means that updating the
Scribus AppImage, e.g., from 1.5.1.svn.20624 to 1.5.1.svn.206245, requires
downloading just 1.4% of the AppImage, as the other 98.6% have not
changed and can be reused.

Tests and feedback welcome.
