API release hotfixes (#2431)

* API release hotfixes

-Fix SQL statement for deleting API keys
-Actually return picid as an integer, like we claim we do
-Capture all path parameters, not just the first one
-Loosen JSON validation for incoming data, because Perl doesn't care

* Fix 'use of uninitialized variable in string comp' warnings

* Use more explicit coerce() instead of deprecated coerce(1) in validator

* make what we're doing a little less obtuse in spots
