 * Copyright (c) 2009 Petr Stanicek (pixy@pixy.cz)
 * version 1.1, January 12, 2009
 * 
 *
 *	Change log:
 *	1.1 - Firefox 2 and older disabled due to wrong inline-block support.
 *
 
- usage: jQuery('#anyselect').styledSelect(options);
- options are optional 

CSS:	.select-replace: border, padding, background, font style
		.select-replace-cover: additional background
		select (the original element): font-size, width

Note:	Try to keep same size of original select and the replacing box - primary by adjusting
		font-sizes and padding, you'd better not to set height/width of those boxes.

Tip:	Use options {opacity:0.1} (or similar low value) to reveal the original select to fit the sizes
		while debugging. Don't forget to set it back to zero when you done.

Note:	If the original select is hidden while caling this function, you must trigger its resize handler
		after you show it first time, e.g.: jQuery('#myselect').trigger('resize')
