Author: York Zhao <[email protected]>

Add `avy-translate-char-function' to translate user input key
This can be useful for adding mirror key. For example, one can make SPACE an
alternative of 'a', by adding:
(setq avy-translate-char-function
(lambda (c) (if (= c 32) ?a c)))
to allow typing SPACE instead of character 'a' to jump to the location
highlighted by 'a'.
Fixes #59
