Population update

Implemented ability to edit and save the population value in a queried
entry.
validation checks

Added validation checks to avoid editing on blank country names.
Failed delete attempt

Executing a non query command DELETE, but from the NET connector, this
query string fails. Typing the 'same' (not exactly) string into mysql
command line interface results in a successful delete.

Possibly try to duplicate the string exactly, case and all in the CLI, and
then make them even closer by removing the prepared statements.

The prepared statements are not exactly necessary, as the use can only
provide successfully input queried stings indirectly.

Conflicts:

Resolved conflicts will require GUI adjustment
Merge conflicts resolved.

Well, I thought I had done more work than was on remote. Turns out it was
on another computer and not pushed.

Going to update all of that now.
Updated delete method

Now we are back to the part where the delete fails to execute.
eliminated unit tests on GUI elements

The tests here are mostly inconclusive and required interaction. The goal
is to divorce the GUI from as much logic code as possible and keep the
unit tests focused on the logic, until I can devise a way to automate GUI
testing (possibly with autikey or a similar script).
successfully added data source to unit test
Added dump for unit test db

Run mysql command on the UnitTestdatabase.sql file to obtain the test db
for unit testing.

The simple database is uded to run the unit tests on so that we cna
eliminate issues from complex database commands and test just the
functionality of the C# code.

The current issue:

The unit test for runNonQuery always passes, though it actually fails to
update or delete an entry.

TODO:
Create a more meaningful return value from this method that can show the
failure. Currently we return the last auto incremented value, but in this
case, that value is meaningless except in the one case where we insert
into a Auto-inc type table.

So create a more testable method and modify its test accordingly.

Possibly want to do this by confirming via unit test that the standard
select type query works as intended. Then use this select to confirm that
the values have been indeed updated or removed during the test.
sln had changed for some reason.
