Parse new single-line skills and add option to parse log differently

The option keeps track of what the last parsed turn was and tries to parse every turn since then.  This is useful because with the old system if you reload the page the latest turn is counted twice, and if you go too fast HVSTAT can't keep up and you miss turns.  I don't really like the option's description text but I can't think of anything better, so if you come up with something feel free to change it.
