support multiple search fields

[shalakhin]

@and3rson I think it would be great if

widgets = {
    'user': SearchableSelect(model='users.User',
                             search_field='email',
                             many=False, limit=10),
}

will be

widgets = {
    'user': SearchableSelect(model='users.User',
                             search_field=['email', 'first_name', 'last_name'],
                             many=False, limit=10),
}

If you agree I will make it.

@shalakhin That's a great idea! We can definitely have it.
Also, don't forget to keep it backward-compatible with single string.

Sure thing I won’t forget about compatibility

@shalakhin seems like this can be done within the scope #10, I'll probably close this issue in favor of #10.
