Added SQL_Utils.java.  Utilities for REUSING a connection, AND easily
modifying, and querying, SQL databases.
Added a loadIntoDB function in the Planet class using SQL_Utils.
Patches to SQL_Utils.  Now usable.  Save operation (for planets) is 40ms slower for ONE-planet saving.  Pending trials for multi-planet operations.
Changes to main() to test speed of THIRTY planets' saving.
Addendum to previous commit.
Fixed a bug causing the ID field of the planetary database's tables to
be of the type "medium text" instead of integer.
Added loadAllFromDB function.  Bugfixes.
