Updated NodeActivity to use the ToggleButton.

NodeActivity now uses the ToggleButton for bookmarks. It will display a
plus when a bookmark is not yet added to the database, and a minus when
a bookmark is currently in the database. Thus, this button represents
the available action they can take on a bookmark.

Updated the application so that it can generate database and all updates

The application will now generate the database on first launch as
opposed to being pregenerated. This will allow for easy updates in the
future via change scripts. Precautions have been taken for all users who
have previously installed the application with the pre-generated
database.

Removed extra variable from NodeDatabase.java

The extra variable was previously used in debug logging for
determining array size for the sql DDL file statements. It is no longer
needed.
