Fix account privilege escalation vulnerability
A check is only done to verify a Trusted User isn't promoting their account. An attacker can send tampered account type POST data to change their "User" level account to a "Developer" account. Add check so that all users cannot increase their own account permissions. Signed-off-by: canyonknight <canyonknight@gmail.com> Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>
