[rfc][icedtea-web][policyeditor] "File - New"

Hello,

Looks good +1. On an unrelated note, I noticed that Add new the second word is not capitalized but in other usages such as Save As or Custom Permissions, the second word starts with a capital, so perhaps the new should be capital too and possibly Copy Url to clipboard, the clipboard could also be capitalized. 

>From your patch, the way you handled the title is great.

-        performingIO = true;
+        setPerformingIO(true);
Good catch to use the method instead.
Anyways looks good and works well.
