Wired up scaffolding to build tests for 95% of the DTS_Core class
Change build_cookie_name to accept the site name as an argument
DTS_Core Singleton change to allow forcing the creation of a new instance instead of reusing an existing instance
Refactored DTS_Core to no longer need a does_need_install method by instead storing the version in an internal variable
Allow activate method to pass it's $force_new_instance variable through onto get_instance
Adjusted the DTS_Core activate function to be more logical
Adjusted the install method so that it updates options. This actually could of been a bug, where installing could fail if the user still had plugin options installed
Corrected two functions which should of been static and were not
Rewrote the get_installed_version method to be more logical
Corrected a bug where update routines would not be run due to a path issue
Whitespace adjustments
Added tests for the install routine and both update routines
