PHP zip bundle has been replaced by zip/unzip command line programs.
Remove submitdaemon, submit client now always uses the REST API.
Remove some unused *SUBMIT_* defines and ifdefs.
Fix PHP notice
If no password entered, keep any old password.
Replace old SUBMIT_* configure variables by SUBMITCLIENT_ENABLED
to allow detection of whether submit client needs build/docs.
Also cleanup submit/Makefile a bit more.
Remove duplicate problem zip upload form: already present on
the problem edit page.
Add possibility to unset values to edit pages, and use it
to allow unsetting problem text.
Suppress verbose output from unzip.
Fix quoting of PHP string.
Fix clang++ compiler warning and break long line.
Fix makefile dependency of mysql_db_files*.sql on problem PDFs
to trigger only when changes
Remove excessive dependencies.
Remove more unused code in submit client.

Setting team on the commandline now unused.
Ifdefs for curl or jsoncpp are not useful anymore.
Remove unused includes and functions.
Example submission via command line curl
Remove configure checks for unused headers.
Move EXITCODES from common-config to judgehost-static.

It's only used outside the judgedaemon for a configcheck, which is
of rather limited value. Moving this removes a needless interdependency
between domserver and judgehost configs. Moving it to -static since
it's not normally something anyone should change.
Remove unused domserver-static.h.in

Also clarify that sudoers is only for judgehost.
transfig no longer needed
just as effective, one third of the annoyance
