Item Can Have Name Set to Empty String in Edit Item Dialog

[johneastman]

When editing an item, a user can set an item to have an empty string for the name. This should not be permitted. Item names should be at least one character.

Solution:

• gray out add/edit item button if an item's name is less than 1 character in length (i.e., an empty string).
• Remove logic checking item name length before adding

I decided limiting what the user can enter for the name of an item is not worth the effort at this time. If this becomes an issue in the future, I will re-open this task or create a new task.
