Know your strings

In a number of recent reviews, I've seen some common mis-uses of 
strings.. we've documented these before, so I just wanted to send the 
link around again.  EVEN IF YOU THINK YOU KNOW YOUR STRINGS, please at 
least look over the first link - it will take you 2 minutes at the most.

The string quick-reference guide:
http://www.mozilla.org/projects/xpcom/string-quickref.html
Explains some common bad patterns and how we should handle them

The full String Guide:
http://www.mozilla.org/projects/xpcom/string-guide.html
A huge brain dump of how strings work, to the best of my knowledge.

I highly encourage people to peruse these documents - strings are used 
in every part of our code, and so every developer working on mozilla 
should be as familiar with them as they are with XPCOM.
