cx_OracleTools Code

Dramatically simplified setup now that most of the code has been included in
cx_Freeze.

Remove extraneous imports.

The locations on the web for the dependent projects has changed.

Move SQL files to subdirectory; ignore any created .egg-info files.

Modify license to include copyright for me personally now that I am no longer
employed by Computronix.

Added new option --name-file which is the same as name except that the names
are listed in the specified file, one name per line.

cElementTree is now built in so there is no need to guard its import; this
means that the code currently requires Python 2.5 in some places.

Use the new property fetchvars rather than depend on the return value of
cursor.execute() which has now been changed to return the cursor itself so it
can be used as an iterator.

Initial support of Oracle contexts.

Update the code to more modern Python syntax as suggested by David Hancock.
