Changes

* [https://bugzilla.mozilla.org/show_bug.cgi?id=336060 336060] - use a slower idleEvent timer for plugins that are not in a foreground tab on the key window

* [https://bugzilla.mozilla.org/show_bug.cgi?id=344427 344427] Support 64-bit Mac OS X NPAPI, as proposed on the plugin-futures mailing list. Significant changes include the option to render via CoreGraphics (QuickDraw will no longer be the only option) and updated native event structures.
