[sldev] Good patch practice

[Jason Giglio]

"Please do not add issue numbers or your name to patches. We have to 
remove these by hand. "

I'm not clear on this part.  Do you not want us to name the patch file 
with our name?   Or not put our name in comments?  I think it's pretty 
important to put our name (or initials or whatever) in comments, so 
people know who to call if they have a question about why that part of 
the code is doing something weird.

Linden Lab devs sign their comments, why would we do something different?
