Created new regression testing framework with a number of testcases (many more
can be added). Also changed 'test' target in makefile to run the new
tester.sh. (Hopefully, we should be able to remove all the tests/*.mk files
soon.)

+# testcases
+#
+# This file should be filled with test cases to test applets that:
+#
+# - can somehow produce output (we can't test sync or sleep)
+# - have a GNU (or other) counterpart
+# - are not interactive (don't require a ^C or anything)
+# - don't require extensive setup or cleanup (a litte setup is fine)
+# - don't have huge and possibly damaging effects (fsck, swapoff)
+#
+# If possible, a test case should be made that tests each option the applet
+# supports. When a new option is added, a new test case should be written for
+# it. When somebody reports a bug with a testcase, that testcase should be
+# added here as well.
+#
+# Some other guidelines to follow:
+#
+# - please try to keep applets alphabetized, it will make life easier
+# - use the file tester.sh or testcases when you need to do a non-destructive
+# test on a file (i.e. cat, md5sum)
+# - try to make the applet you're testing the first thing on the line (this
+# not always possible)
