Fix name attribute of button elements so jquery '.submit()' doesn't break

According to "Additional notes" in:

http://api.jquery.com/submit/

Not fixing buttons created with 'input' tags.
just mark dead hubloc deleted - don't remove them. This could cause problems. Also clean up fetch_url/post_url header option
Merge https://github.com/friendica/red into pending_merge
z_post_url_json() added to easily deal with JSON post APIs; without getting content-type unknown warnings/errors. Also added a debug option to z_get|post_url so you could track and log some of these nasty little buggers.
still some old Friendica database queries in diaspora_signed_retraction
that's why bb2diaspora_itemwallwall() wasn't doing its thang.

no sense maintaining 2 to-do files. I think the one I'm removing is referenced online somewhere - which is why it wasn't done earlier. Can't find it, so just note that somebody will complain and we'll have to edit the pointer someday.
Merge remote-tracking branch 'upstream/master'
