Contacts UI fail to work properly with non-ASCII names

[Roman Yepishev]

The by_letter view for new contacts ui does not work properly with non-ASCII names:
...
 return first_letter.match(/[A-Za-z]/) ? first_letter.toLowerCase() : '0';
...

For example, all contacts with names in cyrillic get grouped under '0' letter/number which is not that user-friendly.
Since that affects all contacts whose first name is not [A-Za-z], this is a pretty major issue.

[Roman Yepishev (rye)]

In order for this to be fixed, the javascript view should have one function updated:

function first_letter(name) {
    var first_letter = name.substring(0, 1);
    return first_letter.toLowerCase()
}
