Add a "is_generic" to detect WvW logs

The wording on the evtc README is

> an npcid of 1 indicates log is generic - triggers by squadmember
> entering combat and not as a result of a boss species id.

It is not quite clear whether "generic" implies WvW or if there are PvE
generic logs as well if you manage to set up arcdps in the right way.
Therefore, the wording in evtclib is rather unspecific as well.
