SimpleSelectStyle v.1.2
Simple select tag styling; cosmetic only.

Author: Ben Stilson

Required:
- CSS class for styling the alternate "select" span / select tags
- select_class option must be defined with CSS class name
- specify a select width, either in the CSS class or directly to the select tag
- use only with single line selects (size=1/default)

Optional:
- to use with all selects in an entire form, provide the form id for the option form_id
- left_padding is used to add left padding (indent) before the text, defaults to 3px
