Fix of the edge case 0 weight that occasionally will pop up in some specific situations. This was crashing the script.

Even though -f enables running webui.sh as root, the -f flag will also be passed to launch.py, causing it to exit with a usage message. This adds a line to launch.py to remove the -f flag if present.

In addition to the above, all the letters in the command line arguments after each '-' were being processed for 'f' and "illegal option" was displayed for each letter that didn't match. Instead, this commit silences those errors and stops processing if the first flag doesn't start with '-f'.
