+ Flay no longer defaults to '.' if no args given. Allows plugins to do more
[git-p4: depot-paths = "//src/flay/dev/": change = 8204]
+ Added --timeout option. Defaults to 10 seconds.
Flay.parse_options now has an args argument. Defaults to ARGV. Good for testing.
+ Added ability for plugins to define options_<pluginname> method to extend options.
+ Moved #analyze down to #report. #process only processes, nothing more.
+ Sort output for more stable reporting. Better for diffing against, my dear.
