experimental hitpointbar change

Browse Source 
For tty, make hitpointbar blink if current HP falls to the critical
HP threshold.  Doesn't require status highlighting.  Not changed:
when status highlighting is active, use the HP color but force the
attribute to be inverse (plus blink if the criterium is met) rather
than whatever the HP highlight specifies.

For curses, do the same thing.  It used to honor HP attribute for
hitpointbar, now it behaves the same as tty:  always inverse, maybe
combined with blink.  The new code assumes that inverse and color
can be turned off without turning off active blink in the process.

I had intended to make hitpointbar be a full-fledged status field
(which happens to be rendered on top of title) so that it could be
highlighted differently from hit points (mainly so that one could
highlight up and down changes while the other showed percentages).
This is less versatile than that but much simpler.
