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.

BUG #14099. Fixes spreadsheet selections with composite datasets.

Fix logic to connect to renderserver nodes.

When running in data-server/render-server mode, the data-server wasn't getting
the information about the hostnames for the render-server nodes correctly and
hence always ended up connecting to "localhost". This fixes that. Now, the
information about the render-server nodes' hostnames is relayed to the
data-server correctly. The render-server nodes' hostnames are determine using
plaform specific API. At the same time, argument --hostname is provided to
override the platform specific hostname for the process (useful for debugging, as
well).

Fix string names for processes in pvx files.

Expanding the string-names in pvx file for process types to include
non-hyphenated versions e.g. dataserver and data-server can now be used
interchangeably.
