Link to Issue Type in 'What is an Issue?' page points to the incorrect anchor

Customer email:
Hello,
on your website (http://www.atlassian.com/software/jira/docs/v3.12/issues.html), in description of second field (Type) there is a pointer to list_of_types, which actually points to Priority Levels.

Fix is to change the link to point at the IssueTypes anchor, instead of Priority Levels.
