Consider zoom when culling billboards.

screenScale represents the current zoom factor, but may need some
revision because I'm not sure if what it's doing is technically correct.
It is used to multiply the culling distance for cells, as well as the
fading distance.
Added comment.
Elastic ease fix

Elastic ease used an arcsinus function where it should have used a sinus
function.

Tools GuiProfile Separation.

This effectively duplicates (where necessary) and moves tools specific GuiProfiles out of the core and into the tools.  This will allow future modifications to either the game guis or tools guis that use these profiles to not conflict with each other.

Removing the controlsHelpDlg to reduce maintenance overhead.
Merge pull request #266 from thecelloman/removecontrolshelpdlg

Removing the controlsHelpDlg to reduce maintenance overhead.
Made the flipped y-axis on terrain import optional.

Pass a final boolean argument to TerrainBlock::import to control
y-axis flipping. It is enabled by default, since this was the previous
default behavior.

This should be added as an option in the terrain import dialog - see
game/tools/worldEditor/gui/guiTerrainImportGui.gui
Adding a basic rule-based terrain painting implementation.
