Add qda/hda to sprints (Lightli)

(Quicksilver dragon armour & shadow dragon armour.)
Unbrace
Add placeholder hda tiles

Simple edits of the storm dragon armour tiles.

...might be a little *too* stealthy....
Add placeholder qda tiles

Simple edits of the mottled dragon armour tiles.

Not sure how I feel about the purple accent on the item armour
tile - might be a little overwhelming?
Oops
Refactor describe_god() a bit.

To get rid of the icky recursion, and keep god_desc_type contained to
the file.
More title tweaks & fix indentation.

Make Cloud Mage a more high-level title (just how much of an expert is
Plog the Cloud Mage, anyway?), and give Jiyva worshippers a "Dissolving"
title as a nod to Dissolution.
Don't try to be so clever about when you should cast spells (#9054).

This reverts commit 6c63de089233b21898f7f25c3ad56a61541e7683.
This reverts commit ec40e5ec1d95582f6eab9ed449aed67055ef9595.
Don't z-cast OTR, Ozo's Fridge, and CL with no monsters nearby.

Hopefully a more selective approach will be less error-prone...
An incredible masterpiece of heartbreaking perfection for player tiles

Legends say that after creating this epic rendition of the mighty
Jörmungandr, the Tile Master ascended to Godhood.

I've made weapon and shield offsets that aren't the natural ones, but
these don't cause visual artifacts in WebTiles.
Add DISALLOW_COPY_AND_ASSIGN macro

This macro is used to disable the copy constructor and assignment operator
for a class.
Add actor::heads().

For a bit more encapsulation of monster::number, and some code
deduplication.
Don't give monsters two chances to decapitate player hydras.
Add HDA/QDA to another missed list.
