Use a custom character map instead of name normalizer
Instead of normalizing names during caching, add a function that that maps accented characters to their alphabetic equivalents using switch statements. This character map is used in the on-the-fly matching algorithm. This speeds up the caching process(11k contacts) from 800-1500ms to about 600-1000ms since we no longer perform the normalizing step during caching.
