BACKLOG-861 Add properties for administrative email and JIRA issue

I've added two configuration properties that define what needs to be sent out when the user presses "ask question".
BACKLOG-861 configuration properties for Email and Jira

Changed Link, Unlink and Question flow with a configuration property
for creating a Jira task and/or sending a email. See JIRA for more info.
fixed stupid typo in property name :(
Added the config options to the environment properties

Also fixed the same typo as before in the member name.
