CAVEEXPRESS: wind indicator in the hud

[mgerhardy]

The map wind value from the map lua script is sent to the client with the MapSettingsMessage protocol message already. The ClientMap::setSetting() method is converting some of them already for easier use. The wind values should also be used here in the hud to show a wind indicator

Currently these wind values are in use

base/caveexpress/maps/desert-01.lua:	map:setSetting("wind", "1.000000")
base/caveexpress/maps/desert-02.lua:	map:setSetting("wind", "1.000000")
base/caveexpress/maps/races-03.lua:	map:setSetting("wind", "1.000000")
base/caveexpress/maps/second-rock-06.lua:	map:setSetting("wind", "-0.2")
base/caveexpress/maps/test-crash-sidescroll.lua:	map:setSetting("wind", "6")
base/caveexpress/maps/wind-01.lua:	map:setSetting("wind", "2.5")
base/caveexpress/maps/wind-02.lua:	map:setSetting("wind", "2.5")
base/caveexpress/maps/wind-03.lua:	map:setSetting("wind", "2.5")
base/caveexpress/maps/wind-04.lua:	map:setSetting("wind", "2")

we need to define a max value where do do the clamping on the server side and then use that value for the 100% on the client side, too

The wind indicator could be something like the one that is used in the worms games e.g. - specify a direction (negative left, positive value right) and the amplitude

I was thinking of adding scene particles, flying in direction of wind.
So on desert: flying sand, on ice just snow, in jungle just rain, on rock hmm maybe some dark ground particles.
Maybe this way we could drop having another bar on Hud? It is getting to be full.

The tree could drop leaves, too

[mgerhardy]

4eaf6ed ff implemented a tree particle when a stone was dropped and hit it. it would be nice if we the (currently unused) Leaf particle could spawn from time to time if the map has wind (without physics attached - the leaf is just flying through the map in this case - so all client side)

[cryham]

Okay I will try adding it to Rock and Jungle probably. In addition to current Sand, Dirt, Snow and Rain from weather with wind.

Done #172
so check out wind particles, I think we don't need now an additional wind bar on Hud. Or maybe on devices.
