The tests weren't complete nor were they being used so I dropped them. Since
this branch is still actively being maintained as it's the PHP 5.3 compatible
stuff I figured I should update the headers to have the current year and
explicitly show that it's PHP 5.3+ and not just PHP 5.
Solves the issue with having a site not using the built in PDO (case in point, I'm building a site entirely on Redis with a separate vendor library that isn't part of PICKLES)
Also obliterated the getters and setters in the Database class after running some tests against their speed in comparison to getting and setting the variables directly
* Logs the input parameters (if available) with the query and slow query entries.
* Uses the new JSON constant to determine if it should use json_encode() or serialize()
* Updated the Database class to work like a Singleton with a getInstance() method.
* The Database class does not have a private constructor so it can still be instantiated in case someone needs to do so.
* Replaced Logger class with Log class.
* Updated Module to have an instance of the Database object as well as the Model class.
* In my perfect vision for usage, the Module classes should never talk directly to the database, but do so via Models, but I know that's asking a lot, so I'm leaving in some options for folks.
* Updated documentation.
* File was little more than just a stub file for the Cache class.
Removed Mailer class.
* Attempting to remove non-critical classes from the system.
* Class will be re-added / re-factored at a later date once the core of PICKLES is done.
Removed Security class.
* Removing non-critcal classes from the system.
* Security class was not very generic and will be replaced down the road once the security scheme is full realized.
Removed Form class.
* Removing non-critcal classes from PICKLES to help the rewrite efforts.
* Form class would take a database table and convert it into a webform. Nice script, but really had no place in PICKLES.
* Eventually will replace with a generic HTML form element generation class.
Added INSTALL file.
Updated derivation of the hostname.
* Hostname is now defaulted in the class variable definition.
