Subject: [PATCH 1/2] Add option to show health bar for all destructible mobjs
References: https://github.com/coelckers/prboom-plus/pull/274

The current health bar fails to show for Lost Souls.
In addition, showing it for other destructible objects (such as
barrels - or DEH modifications in that spirit) can be used to gauge
the objects' remaining life.
