Subject: [PATCH] Fix support mailto link opening a blank tab

Pass target="_self" to the Support menu item so clicking the mailto link
does not open a new browser tab. Also adds the admin email as a title
attribute on the label span, giving users without a mail client configured
a way to see and copy the address on hover.

Closes #2435
