Fixes for the Nektar reader plugin.

Fixes are:
1) Had to add in PLUGIN_NAMES so that the plugin would be
available through the Plugin Manager.
2) Got rid of a bunch of compiler warnings.
3) Suppressed overloaded virtual methods warnings.

Fixing issues with coprocessing.py.

Some parts of the script weren't getting tested (need to fix that
soon) and needed to be fixed to properly import modules. I also
fixed warnings that were generated when UpdatePipeline() wasn't
getting called with a time argument.
