-Elements to remove are now automatically highlighted in the currently
selected sentence (independent of selecting the element from the add
list or remove table)

-"Clear Highlights" button added to bottom of elements to add and
elements to remove, so the user's in control over when and how long the
highlights are in place (not longer automatically deletes them)

-Suggestions Tab code cleaned up, now anything relating to listeners and
actions are handled in DriverSuggestinosTab

-Remove and add highlights now independent of each other

-Preferences updated to allow the user to turn on/off the automatic
"word to remove" highlighting
