Problem: When opening a comment box, there is always a default to "Open an issue" ie that box is checked.

Solution: Create an additional property that is configurable by the user to swap that default on or off.
1. Evolution to add property: open_an_issue
2. Modified all relevant files to allow it to be stored in the database.
3. Made open_an_issue reflect in the comment dialogue when changed in account settings.

The "My account" page saves the preference just fine. 
You can toggle it on and off, and it's reflected on the comment dialogue.
Tested from off to on, on to off.
