[HOT] HOT/HDM web rendering

[Brian Wolford]

Speaking of the preset:
Yes, I agree this isn't truly HDM anymore. It is not just the extra things
used to tag disaster and humanitarian response things. The preset is being
used to coordinate large training and mapping field operations in
development work. I would be for changing the name of it, perhaps to some
thing like "HOT Field Operations Preset"

I agree that the current "HDM" (not for long) preset does have allot of
duplicated work in it. This is bc when coordinating a large project with
people who may be using computers for the first time, you really do need a
centralized resource for all these things. Saying to "use default for these
things, add the office preset, add the craft preset, add the New Wiki Tags
preset, use our personal preset for [cyber-cafe, wholesale, lottery kiosks,
ect], and use the HDM preset !NOT THE DEFAULT! for roads, toilets, and
waterpoints" doesn't work (at least here). We've tried. Having things in a
not centralized location while training so many beginners over large area
leads impossible quality control.

The project preset also allows us to make immediate additions or
corrections to the preset and change troublesome translations immediately.
So yes, I think that this preset is in sense more of a "project" preset and
the name should be change. And that this preset should be a good reference
for dev world and re-evaluated with each project (HOT or otherwise).

I also think "pure" HDM should be diven into again. I would like to look at
refugee camp tagging again specifically.
