arguably better defaults for tabs and pairs

Because of JuliaIDE/Julia-LT#167
and http://discuss.junolab.org/t/german-keyboard/126/10

Maybe this should go along with some instructions to get the paired brackets to work again.

So this one's a bit tricky because you have to make things inconvenient for someone. LT went with what you're suggesting, to get rid of the pairing. I figure it's probably better to fix the problem, rather than hiding it.

Maybe a better stopgap would be to detect a german keyboard layout and then disable pairing?

Sure - if you know of a way to reliably detect the keyboard layout, that'd be a better solution (unfortunately I didn't find anything about that).
And if there's no way to automate this and we have to rely on user input, this is as good a way as any.

The best solution though would be to fix the underlying issue... Possibly relevant issue.
A possible solution would be to add an option to detect charcodes (e.g. 91 for [) instead of keycodes because that would be universal for all keyboard layouts. Then we could do something like [:editor.keys.normal "[" (:editor.open-pair "[") :charcode] and get the desired behaviour across the board.
The other behaviour is still needed so that specifying a modifier still works.
