Support hotswap functionality

[GoogleCodeExporter]

I am not intimately familiar with the way servlet containers are architected, 
so I may be using the wrong words: I apologize.

What steps will reproduce the problem?
1. mvn appengine:devserver
2. update some code
3. mvn compile

What is the expected output?
devserver scans for changed files periodically, and reloads them.

What do you see instead?
need to stop the devserver and start it again for the changes to be seen

Some people have success with this, but you'll need to do mvn package instead 
of mvn compile, since compile doesn't actually construct the war contents.

looks like something changed in 1.8.1
I see this in my log now, and I don't remember seeing that when using 1.8.0

This does seem to be working for Java code now, but it would really be 
beneficial to have the HotDeployScanner update static files as well. It is 
crucial, actually, for an efficient javascript debug cycle.
