Statistics pages updates and more searching/results work

- Updated all the statistics pages to be HTML5 compliant
- Updated some statistics stored procedures for speed and ability to handle looser aggregation hierarchy (finishing work started years ago)
- Updated some statistics pages to use jquery Datatables for sorting, etc.
- Updated collection selections in stats pages to have an option to select by code or by name
- Removed references to the static GO image and replaced with CSS in statistics pages
- SobekCM_Stats CSS created and most formatting pushed into stylesheet, from in-line
- Searching by date range now works, but still need to add search UI to include date range boxes
- Recent searches now keeps the last 100 searches, rather than last 50
- Corrected issue with the Type Format metadata entry element which was not keeping Aerials correctly
- Corrected issue in citation added in last version, where the Publication Date row appeared, even if there was no data
- When uploading TIFFs with a new item, JPEG and JPEG thumbnail are now created on the fly, matching what happens when you add a TIFF to an existing item
