4 minor changes to the /admin/input/ for data-loaders.

1.) minor adjustments to the admin/input. Re-arrange the fields so that it says:

2.) Change 
Review your added item in the 'Items Added' tab now is blue color and in a banner so it's more noticeable. 

3.)Category for these Pins: moved down so that it's right above all the fields for the data-loader.

4.) For the tag field, if you put #benz, the item became ##benz with (2 #). Added a check to have one # in front of each tag, and automatically removes ## when saved to the DB.
