implemented empty status

If every field is blank, the status will appear as empty.

Extended the bit flag to accommodate for this. In the future, it would be possible
to validate for specific fields being empty to affect this status instead.
implemented tooltips

Tooltips will show when a field with any warnings or errors is hovered
or if any of its labels (text to its left, or a status detail) are clicked.

Fields with warnings and errors will also change border color if hovered or
focused to better show this.

This will need to be updated to process tooltips for cards with quantities in
excess of 4 and unrecognized lines are properly implemented for the status box.

**NOTE:** jQuery UI updated to 1.11.2; added tooltip.js
