[ATLAS] brush shapes and tile/vertex styles

[Philip Taylor]

See patch from #83. Putting discussion here since it's not related to that ticket.

Thanks, this looks mostly good, but there's a number of issues I've noticed from quick testing and reading that should probably be fixed:

• Start editor, click Terrain, change size, get JavaScript error: section/terrain.js line 51: TypeError: this.tool is null
• When size=1, vertex brushes don't render at all.
• Tile brushes seem to be offset by half a tile from the mouse, particularly visible when size=1 (it ought to highlight the tile which the mouse is in).
• The vertex brush looks a bit funny to me, but I suppose it makes sense. Maybe the dots should be white instead of green, else they're a bit hard to see on the green tiles on grass.
• Whitespace/newlines in code like if(m_Brush->IsTileBased()){ ought to match the surrounding style.
• There's some commented-out bits in a Brushes.cpp that look like they should be deleted.
• New methods in TerrainOverlay.h should have some brief documentation.
