Tb2 menu reference: first draft

I've just uploaded the first draft of a menu reference page for 
Thunderbird2, and I need feedback/review.
<http://www.mozilla.org/support/thunderbird/menu>

Most of the content is taken from 
<http://wiki.mozilla.org/Thunderbird:Help_Documentation:Menu_Reference>; 
but the wiki page is missing many newsgroup items, has unfilled 
definitions, and is out of date.

Given what I've added vs. what is on the wiki page, there are probably 
some consistency issues, spelling issues, grammar issues, and menu items 
in different spots on non-windows operating systems.

Tracked by bug 374257. <https://bugzilla.mozilla.org/show_bug.cgi?id=374257>

Follow-up set to mozilla.dev.documentation.
