* 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`.
See updated `readme.md` for details.
* bug fixes:
* fixed directory-existence argument check
* fixed how `.urchin_stdout` files are cleaned up
* fixed instances of error/warning messages outputting to stdout instead of stderr
* documentation, help and error-message improvements:
* added specific error message if the (non-option) argument is not a directory
* improved wording of CLI help
* readme.md: replaced obsolete URL http://www.urchin.sh with https://github.com/scraperwiki/urchin
* readme.md: made the fact clearer that `./cross-shell-tests` only tests urchin's _own_ cross-shell compatibility
* HISTORY: fixed typo
* formatting and logging improvements:
* added timestamp to the beginning of log files (`.urchin.log`)
* captured output from failed tests is now printed in *red* to draw attention
* test summary now prints the number of failed tests in the appropriate color for instant feedback (green, if none failed; red, otherwise)
* cleanup
* removed unused test files, simplified some tests
