Support Pale Moon browser in out-of-date dashboard widget

[Daedalon]

The "Your browser is out of date!" notification in WordPress dashboard is shown erroneusly for Pale Moon users.

Pale Moon is the most popular optimized version of Firefox, and its version numbering scheme runs a bit different from the mainstream Firefox. The current version of Pale Moon ​http://www.palemoon.org/ is 15.3.2, which is just as up-to-date as Firefox 17.0.1.

Summary of the issues:

1. The version check should be done against Pale Moon version number instead of Firefox version number.

2. The text and links should refer to update Pale Moon instead of Firefox.

Can you please provide the full user agent string for the Pale Moon browser?

Here you go: Mozilla/5.0 (Windows NT 5.1; rv:15.3) Gecko/20121202 Firefox/15.3.2 PaleMoon/15.3.2

I think we should wontfix issue 2. Pale Moon is not popular enough to warrant an exception.

That said, issue 1 could be fixed by doing a better job at detecting Firefox in related UA strings.

There's nowhere near enough users using the browser to justify this. Closing as wontfix as suggested in previous comment
