How to enable mail.tabs.drawInTitlebar

[skjerns]

How exactly do I get to the flags page in Thunderbird and enable this option?

Maybe this could also be added to the readme for not-so-experienced users

There is an open pull request (#10) which will hopefully make this requirement unnecessary, so I won't add this to the manual for now.
