Added a list of outstanding projects that would benefit lldb.

This was a list that I've had kicking around for a while, and would 
add to whenever some hallway conversation would bring up another good
idea.  It's not doing any good on my desktop, but it might generate
some inspiration here.  Please add to this if you have any other
good ideas.

I apologize for the formatting, but if I wait to get it looking
nice it would probably stay on my desktop.
