#740448 by patrick2000, greg.1.anderson, kotnik, Owen Barton: Fixed tput errors when running 'drush' script in cron.

#918468 by greg.1.anderson. Drush should use php.ini files in drush conf folders + some fixes for drush paths that contain spaces (e.g. on Windows)

#662926: Pass --php to drush.php from drush script, but do not propagate --php flag in drush_redispatch_get_options

Revert change to supress tput error message, since the terminal redirection appears to break it's detection.

#441470 - Bevan - drush wrapper should pass parameters. Also fixes working directory and a typo in README.txt

Adding some logic so the script finds drush.php even when called via a symlink. This needs some testing on OS X, since that has a non-standard readlink command.

#441470 - Adding 'drush' script for systems with bash-compatable shells, that will find and run drush with the most appropriate php executable.
