Large decorator / map / model patch:

Decorator:

• Added option to disable envelope rendering in plant tool (Decorator options / Draw envelope).
• Clean up cursor rendering to not obstruct editing (disabling it when envelope are drawn etc.)
• Added "pointer" envelope to select and modify tool which select one entity
• Added "skin groups", which are similar to player pants/shirts colormapping. A 8-bit skin num (0-256) is divided into 2 parts, first 4 bits and the last. First ones set the skin num (0-15). Second one sets the skin group (32 - 1, 64 - 2, 96 - 3 etc., 16 groups possible).
• Transform tool: New "Randomize parm" mode. Which can randomize yaw, skin, skingroup (num and group).
• Rewritten brush presets saving routines to be safe (does not overwrite while brush, just the presets).
• Plant tool: scale are not saved in brush presets.
• Plant tool: new "distribution mode" parm which can be: Explode (default old distribution method), Thin (new one, based on different formula) and Thin 2 (based on different randomization mode which randomly excludes entities from brush instead of increasing coverage radius).
• Plant tool: density not can be up to 1000%
• Brush constructor: improved the way layer radius works. A number is fixed radius (old behavior), "auto" is automatic radius (calculated from model bounds), "auto*value" - scales the automatic value. "auto+value" - adds a fixed value to automatic radius, "auto-value" - same but subtracts.
• Brush constructor: increased max models for layer from 8 to 32.
• Brush constructor: possible layer decoration groups are not parsed from decorations.txt- Brush constructor: max presets now 6 (was 5).
• Transform tool: added option to disable movement tracing for "Offset" mode
• Transform tool: changed back step key to "ctrl+space"
• All folders under "maps/" are now excluded in all file select menus. Cos there are only lightmaps, nothing really useful.

More small cleanups

Bloodmap:

• support for .skin files for all models (even ASE) which acts like surface shader auto-remapping
• now there can be up to 9 _foliage.reg files (_foliage, _foliage2, _foliage_3 ... _foliage9), which are added sequentally.
• ProcessDecorations: fix a crash with empty groups.
• misc_model: new "_pushvertexes"/"_pv" field which stands for "fatboy" modificator - vertex origins get pushed by their normals. Value can be both negative and positive.
• misc_model: new "uvautoscale"/"_uvas" field which auto-scales surface texture coordinates by model scale. Useful for variable-scale stone models.Big models cleanup:
• New "models/surfacemodels" directory which holds decorator-placed map models.
• models/plants rearranged to get different models in subfolders - models/mapobjects/spikes move to surfacemodels/spikes- models/debris/cobblestone moved to models/surfacemodels/cobblestone (sicne debris are for in-game models to be spawned at object destruction)
• Rebuild maps that was affected by cleanups
• Fixed decorator brushes that was affected by cleanups

Decorator-placed stones:

• New "cobblestones" brush as an example of stone placement brush.
• Cobblestone models now using skin groups to cover foreground (stone general) and background (stone bottom) textures. Skin num can be 0-2 (rock, rock2, rock3). Skin group can be 0-3 (grass, ground, mud, sludge).
• Added "surfacemodels_stone" decoration group with UV autoscaling enabled

Other:

• Added test.picoterrain model (and test-picoterrain map) to show an ancient technique to make terrains from heightmaps introduced in q3map2 in 2004. This is pure history, no real usage by Blood Omnicide since this model format wasn't finished.
• Cleaned up models/plants (added grass.ase source file).
