Cleanup and modernizing of gemspec.
Tweaks to readme information.
Change to regexp matcher for quoted parameters.

The regexp for quoted parameters was generated as "(.*?)". This has been
replaced with "([^"]*)", which is a much less 'greedy' option in terms of
what it will recognize. This changes simply makes the regexp a little more
focused.
Removal of sequences functionality.

The notion of macro-type steps -- sequeneces -- was an attempt to provide
a solution for something that may not even be a problem. An extra layer
of complexity was in place for very little apparent gain. This concept can
be revisited at a later date.
Small cleanup of code; improved some output statements.
Removing Cucumber changes to default options.
