[development] 5.0 Core Theme Update

[Rowan Kerr]

For several radio stations across Canada, our browser usage is
something like this:
90% IE (97% IE 6, 2% IE 7, 1% other)
8% Firefox
1.2% Safari
0.6% Netscape (mostly versions 7 and 8)
0.2% Opera

And for operating system:
98% Windows (86% XP, 11% 2000, 3% 98)
1.8% Mac
0.2% Linux/Solaris/BSD

Internet Explorer on Mac usage was barely a blip on the radar:
Internet Explorer 5.23 - Macintosh PPC 0.04%
Internet Explorer 5.17 - Macintosh PPC 0.02%
Internet Explorer 5.0 - Macintosh PPC 0.01%
nternet Explorer 5.22 - Macintosh PPC 0.01%
Internet Explorer 5.16 - Macintosh PPC 0.01%

For security reasons alone, IE Mac should be avoided, and that is
reinforced when looking at the usage. It does not make sense to expend
resources to support it.
