keymap: alt-tab (C-tab) now emits “ESC tab” by default

Browse source 
In our default mode (roughly equivalent to XTerm’s modifyOtherKeys=1),
alt-tab now emits ESC-tab instead of CSI 27;3;9~.

When modifyOtherKeys=2 is enabled (CSI >4;2m), alt-tab emits the “old”
CSI 27 escape.

This better matches XTerm’s behavior.

Note that other alt-tab combos are ambiguous in XTerm, and thus they
are left unchanged here (i.e. we keep emitting CSI 27 escapes for
them).

Closes #900
