Add a minimal test suite
Introduce a new "test/" sub-directory that contains tests for calcurse. Right now, it only includes the quick-and-dirty "run-test" helper that can be used to run and verify tests: $ ./run-test test-1 test-2 test-3 test-4 Running test-1... ok Running test-2... ok Running test-3... FAIL Each argument passed to run-test must be a test script located in the current directory. run-test invokes each script twice and passes the command line argument "expected" and "actual", respectively. A test case succeeds if both "expected" and "actual" instances return with a zero exit status and produce exactly the same output. It fails otherwise. run-test terminates with a non-zero exit status as soon as one of the test fails. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
