[jQuery] Metadata and firefox 3.1beta2

[maxbnet]

Firefox 3.1b2 has a problem with \n.

Test OK
<div id="test1" class="metadata {type : 'p',colors : ['5131C9'],size :
'300x200'}"></div>

Test KO
<div id="test2" class="metadata {
        type : 'p',
        colors : ['5131C9'],
        size : '300x200'
}"></div>

you can use this solution to fix this bug:

cre.exec( string.replace("\n","") );
