cx_OracleTools Code

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.

The bdist_msi command is only available in Python 2.5 and up; earlier versions
of distutils set up their compiler differently; ignore the cElementTree module
in Python 2.5 and up but ignore the new name in earlier versions.

Use MANIFEST template rather than hard coded MANIFEST.

Add support for dumping CLOB, BLOB and binary data values correctly; also added
the commit statement at the end for convenience.

Tweak the build options a bit more in preparation for an actual release.

Allow for the building of the project and the building of any dependent sub
project as needed so that they do not need to be installed; also add these
paths to the environment so that they can be used when building RPMs.
