New ctrl+V command to show monster HP, and other HP colouring improvements. (nfogravity)

https://crawl.develz.org/mantis/view.php?id=5376

Pressing ctrl+v in console will colour all monsters based on their HP. This
can be useful when fighting large groups. This mode deactivates itself the
next turn, or you can toggle it off manually by pressing ctrl+v again.

Zombies and skeletons are given lightgrey colouring, since you can't
determine their HP.

There is also a new option, enemy_hp_colour, which lets you define custom
colours (applies to the ctrl+v display and the regular monster list).

The old ctrl+v command (show equipped weapons) has been removed.
