Remove third-party app prompt

[Pantyhose-X]

Please remove this feature permanently. It is annoying that it pops up every time you open a new website.

It only does that once per domain. It then remembers your decision. This should eventually be improved whenever we manage to deliver Domain Settings #159 .

This has been fixed. You can now define the behaviour you want from Menu > Settings > Domains > Default > Launch app.
You can also override the default settings for each domain.
