Added readline support. Capture now writes out files in command-line vision. Tracebacks only are displayed when the --debug option is set. Timing information is only displayed when the --timing option is set. Locations of supporting directories and the root test directory are providable on the command line. The maximum_wait and acceptable_wait values can be provided via command line options. Tests to be run can be set by arguments on the command line.

Fixed up "show input" format
Fixed a bug where typing "next command" at the end of a file would cause all subsequent files to run, rather than running one command at the start of the next file.
