James R bced5ecbc5 Render precip through blockmap instead of during BSP
There can be very many precipmobjs in a sector. During BSP
rendering, for each sector reached by BSP (the entire
visible level at least), all the precipmobjs would be
iterated and their distance from the camera calculated, to
determine whether they are within draw distance.

The issue with the old approach is that there really are
too many precipmobjs in each sector. By iterating the
blockmap within a certain range instead, precipmobjs
out of view are not iterated at all, saving some time.

Caveat: drawdist_precip is no longer respected as an
exact value, since it must round to the precision of the
blockmap.

List of potentially scary changes:

- Removes snext/sprev for precipmobj_t
- Removes preciplist for sector_t

- Adds bnext/bprev for precipmobj_t
  - mobj_t and precipmobj_t field offsets are symmetrical

- Modified P_SetPrecipitationThingPosition and P_SetThingPosition
  - The syntax in these functions is kind of wacky
