re-written LogLine to evaluate information lazily for performance improvement.
can also detect date starting later in the log line.
mlogfilter now using LogLine extraction (#11). Also fixed milli second support (#9).
stop parsing for datetime after first 10 tokens to avoid parsing very long lines.
updated mlogmerge to work with new LogLine implementation.

renamed connection to thread, fixed thread extraction, operation+namespace extraction does not depend on thread extraction anymore, just on datetime offset.
