This commit adds the file drjava/lib/asm-all-5.0.1.jar which was inadvertently untracked because of an erroneous entry in drjava/.gitignore.
The commit also adds to new .gitignore files to clean up git tracking and
includes some minor changes (formatting only?) the reduced model classes.
This commit adds the .gitignore files that I thought were committed on
the last commit.
