* Tweak: payments types (basic, words, visits, images, comments), when unchecked, have their details hidden.
* New: error handling class and debug features. Errors get logged when PPC_DEBUG_LOG is true (some errors get logged anyway) and detailed errors data is shown when PPC_DEBUG_SHOW is true (lines 42-43 of post-pay-counter.php). Not all errors have been updated to use the class yet. See the errors log in the Options page.
* Fixed: update had broken tooltip info feature.
* Fixed: problems when the image/comments lower threshold was set but the upper threshold was left to zero.
