/*
 
Project:	Input Placeholder Text
Title:		Automatic population of form fields with contents of title attributes
Created:	13 August 2005 by Jon Gibbins (aka dotjay)
Modified:	13 November 2006 by Jon Gibbins (aka dotjay)
 
 
Potential additions:
 
Add in handling of default text if an initial value is detected (line 60, line 93, etc) using something like:
if (!el.defaultValue) continue;
el.onfocus = function() {
	if (this.value == this.defaultValue) this.value = "";
}
el.onblur = function() {
	if (this.value == "") this.value = this.defaultValue;
}
 
Notes:
 
Add the following classes to text inputs or textareas to get the desired behaviour:
 
auto-select
	Will pre-populate the input with the title attribute and select the text when it receives focus.
 
auto-clear
	Will pre-populate the input with the title attribute and clear the text when it receives focus.
	Note: if auto-select and auto-clear are set, auto-select takes precedence.
 
populate
	Will just populate the input with the title attribute.
