KEY-LO bug fix.

Thanks to BDtetra for detailing this issue.

I fixed the bug that allowed line-typing in the middle of player actions, which did indeed soft-lock players, and was probably a very frustrating experience. I also played another thousand or so rounds to be very sure it was fixed. In the process, I incidentally found a few more scoring bugs that I felt it necessary to fix:

>failed un-lock results in -2HP
>concede at 1HP now causes the game to end (for some reason it was not checking health here).

In the event that this is the last game-breaking bug, then consider the weird game logic behavior a result of Kagi's shoddy programming  ;)

My apologies again, and thank you for your patience.

I may take another look at a rare cutscene bug if it is reported again. Otherwise, my focus will be on a very stubborn mulberry tree I am trying to excise from the earth.
