User-submitted text upload was removed in 2779512c6e in preference of
the bugtracker.
Remove leftover mainmenu.js function that this commit should have
removed.
Profiler data upload was disabled in b9e46f386b because the data amount
was too large and because the two timing snapshots are inconclusive
without further data.
The hereby removed exposed JS functions could have been exploited by JS
mods to upload 0ad userdata to arbitrary places.
The performance data upload feature can be redesigned, implemented
without JS exposure, with a more transparent privacy policy (refs
#5257).
