Build: fix distribution of static files for web UI
    
    Static files from Git which are not touched by the build system
    have to be explicitly listed in Makefile.am so they get into tarball.
    
    EXTRA_DIST lists whole sub-directories with static files.
    This is not ideal but we do not have enough time to fix it properly.
    
    Dojo builder patch files were renames to shorten their name.
    The original names were exceeding autotools length limit.
