refs #91 & #124 Doxygen, override, and comment fixes in network.

Changed FILE_PATTERNS config in Doxyfile so Doxygen only looks at headers, not cpp files.
Reverts some changes of commit:116db9a (e.g. terminate() is an internal signal of CNetworkVatlib, but still needs a doxy comment because all signals are public).
