if $TMPDIR is defined set java.io.tmpdir=$TMPDIR.

Java ignores the $TMPDIR variable. This surprises

as the temporary directory.

Fixes #223.
Make SERVER_STARTUP_ARGS readable.
Upgrade gadget rendering server to latest. This will make Go trusts CA signed certificates by default when rendering a gadget from external server. And will make card activity gadget works when pointing to a Mingle SaaS instance (Which is currently broken because Mingle SaaS instance reponses involves different certificates from different services)
