Brushes now get auto-generated names. Fixes #75.

Auto Generated Brush Names

It creates clean brush names like:

• Cube Brush
• Sphere Brush
• Cylinder Brush
• Prism Brush
• Icosphere Brush
• Cone Brush
• Custom Brush
• Trim Brush
• Linear Stairs Brush
• Curved Stairs Brush
• 2D Shape Editor Brush

It then adds the bounds of the brush behind the name, for example:

• (2 x 2 x 2)
• (1.75 x 1 x 1)

There's more!

• Duplicated brushes no longer have "(1)", "(2)", "(3) (1)" behind their names.
• If you give a brush a custom name, it will stop auto-generating one.
• Just rename it to an empty string and it will auto-generate again.

Resulting in:

Fixes #75.

Have you tested this against the test scene with a thousand brushes in, might be worth checking against levels with high brush counts if this dramatically increases scene load times or slows down interactivity

[Henry00IS]

I have tested it against Temple several times with and without that statement and it makes no difference to the tool performance and loading time of the scene in the editor (~ 9 seconds).

PrimitiveBrush, GroupBrush, StairBrush, TrimBrush, CurvedStairBrush and ShapeEditorBrush all have [ExecuteInEditMode]. Essentially all of them except the abstract CompoundBrush. I went ahead and cleared my logic from BaseBrush.Update() as it's no longer necessary as well.

All it does now is a quick name comparison when the scene loads or when a brush is created.
