javascript internationalized strings must be escaped

Javascript internationalized strings must be escaped since the translation may contain quotes.

For example, let's open templates/CRM/common/enableDisable.tpl:

var text = '

{ts}Enable Record{/ts}';

becomes in french

var text = 'Activer l'enregistrement'; <== error! There is a quote in the string...

I added a new Smarty block called escapejs. Now the string is escaped:

var text = '{escapejs}{ts}

Enable Record

{/ts}{/escapejs}';
becomes
var text = 'Activer l\'enregistrement'; <== OK!

If this solution is accepted, it is necessary to add the {escapejs} block to each template containing inline javascript.

Another way to do it would be to add a parameter to the {ts} block:

var text = '{ts escapejs=true}Enable Record{/ts}

';

What do you think about it?
