SW-63. Add logging configuration for openTunLinux

openTunLinux.py -- Changed name of logger so first character is lower case,
for consistency with openTunWindows.
SW-61. Make openTunLinux handling of v6ToInternet event like Windows impl.

openTunLinux.py -- Add try/except handler, and throw ValueError.
openLbr.py ------- Use dispatch() rather than _dispatchProtocol() for
v6ToInternet signal since function call does not use return value.
