update include statements to use new pluginlib and class_loader headers

[mikaelarguedas]

Disclaimer: This in an automated PR, if it is not relevant on this branch, apologies for the inconveniance, feel free close it.

---

pluginlib and class_loader headers have been refactored and renamed. The previous headers .h have been deprecated in favor of their .hpp equivalent. The new headers are available on all active ROS distributions and the deprecated ones will be removed in a future version of ROS (likely ROS-N).

This PR migrates the include statements to use the non-deprecated ones and should compile for any active ROS distribution starting with Indigo The migration was done by running the scripts pluginlib_headers_migration.py and class_loader_headers_update.py on this repository.

@mikaelarguedas Is the new header now available in kinetic? #16 fixed this on melodic, but I didn't do the same in kinetic because class_loader.hpp didn't seem to exist.

Yes these headers have been released in indigo, kinetic, lunar and melodic. Some have been available on the main repository only since the last sync (a few days ago) so that may be the reason.

Just double-checked locally just in case :) :
