Change lint.sh to put Eastwood output in separate file for each project

as well as allowing lint.sh >& out.txt to save all of them in one big
file.  The individual eastwood-out.txt files for each project are
useful for comparing their reflection warnings against the separate
output of 'lein check' for each project.
Add cmp-reflect.sh bash script to compare reflection warnings
between Eastwood and 'lein check' output, attempting to ignore
duplicates and making it easier for a person to see if the only change
is differences in line/col in the warning messages.
