[469b] UnrealEd: Add handful edit for PolyFlags

[SeriousBuggie]

Moved from: https://www.oldunreal.com/phpBB3/viewtopic.php?f=42&t=4432

Will be good if code of Actor Properties window contains special case which allow edit PolyFlags without external tools.

For example on value PolyFlags = 67109132 you simple press "+" and open subitems like in vector, with flags which you can set/unset to modify PolyFlags number.

Flag       Name       Description
0       Default       Use settings from Surface Properties for each individual surface of the brush.
1       Invisible       All surfaces of the brush are invisible
2       Masked       Use for palettized textures to make the first color in the palette (in Paint Shop Pro at least) invisible, see Color Blending
4       Translucent       Darker parts of the textur become transparent, see Color Blending
16       Force View Zone
64       Modulated       Greyer parts of the texture become transparent, see Color Blending
128       Fake Backdrop       Parallax SkyBox visible through surface
256       Two Sided       Surfaces display their texture from both sides
512       U-Pan       Texture moves in U direction, change speed in ZoneInfo or LevelInfo [ch8594] ZoneLight
1024       V-Pan       Texture moves in V direction, change speed in ZoneInfo or LevelInfo [ch8594] ZoneLight
2048       No Smooth       Square pixels
4096       Special Poly       Doesn't do a lot
8192       Small Wavy
32768       Low Shadow Detail       Reduces shadow detail; in conjunction with High Shadow Detail (below), makes extra low shadow detail
262144       Dirty Shadows
524288       Bright Corners       No dark shadows at the edges of the surface
1048576       Special Lit       Surface only gets light from Special Lit lights
2097152       No Bounds Reject
4194304       Unlit       Surface ignores lighting and is fullbright
8388608       High Shadow Detail       Enhances shadow detail

For example you can uncheck "unlit" subitem and 0x4000 (4194304) will be removed from PolyFlags.
