useorocos: maintain a list of exported targets and include directories in orocos_generate_package

This lists are used if orocos_use_package is called for a package within the same workspace
instead of invoking pkg-config. This allows users to generate and use packages within the same workspace.

UseOrocos: adding pkg-config path for catkin workspaces which have yet to be source'd
useorocos: renamed OROCOS_DEFINED_TARGETS to ${PROJECT_NAME}_EXPORTED_TARGETS because this nicely integrates with catkin. Added ${PROJECT_NAME}_EXPORTED_INCLUDE_DIRS for typekits.
