encodeForm function submits all checkbox elements' values, even if some are not checked

[knave]

<input type="check" name="test" value="1" />
<input type="check" name="test" value="2" />
<input type="check" name="test" value="3" />

It will submit as "test=1,2,3" even if only one or none is not checked.

*Tested with nightly release (27/9)

In src/io/BrowserIO.js, line 49 should read:

}else if(dojo.lang.inArray(type, ["radio", "checkbox"])){

NOT:

}else if(dojo.lang.inArray(type, ["radio", "checked"])){
