Subject: [PATCH] Add neutral SUBMIT_OPENER hook to the submit target

The 'make s' submit step now delegates to an executable $SUBMIT_OPENER
(default ~/.local/bin/submit-opener) when one is present, and otherwise
opens the submit page exactly as before. This lets an individual swap in
a personal opener without editing this shared file. Also gitignore
.local/bin/ where such an opener is installed.
