Eclipse Mail initial build

Since I'm having trouble with one of the features I want to bring in the next release of r3dfox, I figure I would get my UXP builds released.

This is a build of Interlink/Mailnews with added features and optimizations.

Improvements over roytam1's Mailnews build:
Installer version and true portable version.
More optimizations.
Compatible with IA-32 i686 class hardware.
Uses SQL instead of DBM for better compatibility with upstream profiles.

The portable builds are fully portable, the profile directory is inside the browser folder. It does not touch appdata at all.

Notes:
This is a bit out of date because I forgot to rebase, shouldn't be an issue though.
I am unlikely to consistently update this application.
Probably more that I have forgotten by now.

This works as far down as XP. My main test platforms are XP SP2 x64, 7 SP1 x64, and 2003 x86 in Bochs emulating an IA-32 i686 class CPU. I believe this should work fine on all versions XP SP2 and later. Haven't exactly stability tested this nor do I know how to.

Please let me know what bugs or issues you encounter with it.
