Upgrade dependencies versions.
Merge branch 'asm-upgrade' of https://github.com/cheeseng/scalatest
Bumped Scala version to 2.10.3, because can't build in 2.10.0 anymore
on my podunk 8GIGABYTE computer. 2.10.3 has that bug fix that eliminates
the memory leak that hurt ScalaTest builds a lot, so that solved it.
Also reduced mem to 4G in ant file, and bumped the ScalaTest version
to 2.0.1-SNAP6.
