Quick fix to be compatible with klout API v2
Bug fixes -- ranking is back on track!
Update insertion of users to match new Klout API

* Add column 'kid' to store unique klout id associated with a twitter handle
* Replace the 1 apiv1 call to 2 apiv2 calls (1 to fetch klout id, 1 for score)
* Add "insert" code in another file, model.php so the same code can be used for submit.php & import.php (with the addition of the extra API call to fetch klout id, we better store the klout id; it's better that we fetch the klout id right away, upon inserting the user - whether over submit.php or import.php)
Split Klout calls into separate class
Update refresh (& force) to Klout API v2

* Move Klout calls into separate class
* Move similar refresh.php & force.php code into (shared) Model
* Update force api call to use klout id instead of twitter handle
* Refresh batch update was not fully implemented (only updated first 100), now is
Use Klout's weekly delta instead of checking score changes ourselves
Add self to list
When using Klout's delta, we can set it upon import/submit already
