[ERROR] Change in Avalon build script

There is a problem due to the recent change in Avalon's build
script.  The build directory for the Avalon Framework jar file
has been changed.  As a result any build in Excalibur that looks
for it in the old place will have an infinite recursion happen
because it is looking for the framework jar in "build/lib"
instead of "target/lib".

Logger is one such victim.  We need to fix this ASAP.

BTW, when did this happen?
