exception messages

[Greg]

Awesome, that's more informative than the API docs would have 
been anyway.

BTW, another API docs problem I noticed is that on the main page, 
the module list in the sidebar doesn't match the module list in 
the page content (the sidebar has more modules, including 
std.exception).

Thanks!
