#182 [askuserinfo] broken html output

[Tomas Kuliavas]

askuserinfo v.1.1 plugin prints "You need to supply your full name and email address" message in optpage_loadhook_personal hook. This hook is executed before html output is started. Plugins should not output messages in this hook, unless error is fatal and plugin stops further code execution.

optpage_loadhook_* hook notices are printed before DOCTYPE tag and break html formating.
