Michael Klement 1e9611e732 Support for cross-shell testing added, via option -s <shell> and env. variable TEST_SHELL. ... * For **tests that _source_ shell scripts**: **option `-s <shell>`** now tells urchin to invoke test scripts with the specified shell (only shebang-less and `#!/bin/sh` tests scripts). * For **tests that _invoke_ schell scripts**: instruct users to write their tests to always **invoke via environment variable `TEST_SHELL` (e.g., `$TEST_SHELL ../foo`)**, and invoke urchin with that variable defined as needed, e.g., `TEST_SHELL=ksh urchin ./tests`; urchin defaults `TEST_SHELL` to `/bin/sh`.
