Rebind "back" function

[Xetaxheb]

Currently, inherited from bqtweaker I guess, this allows you to go back to quest tree with backspace

But either there is no option to rebind this or I can't find it

I would love support for right-click being an option or built-in a-la old HQM, at least from quest details back to tree. Going all the way back to main menu probably wouldn't be useful.

Since it looks like this fork is no longer receiving updates and/or the missing BQTweaker changes aren't wanted, I've went ahead and branched BQTweaker into BQUTweaker to add the missing changes to BQ Unofficial.
