query screen could use readability improvements

[margsuarez]

request for some readability improvements in the query screen. example: search for address:"30th"

• a vertical scrollbar (list window might not fit on one screen)
• perhaps number the entries and display total, so you'll know you need to scroll
• make character display limits for some columns, eg Unit is too long for #9173, max 10 chars? can always double-click to expand

•
