Changed LogDisplay to use the full message for IgnoreIdentical.
Fixed Course::GetTotalSeconds to work on courses that don't have a medium difficulty.  A course with only double charts was probably the one that made the crash manifest.
Added Sprite::NewBlankSprite for use by NoteSkinManager.  Removed default texture loading from Sprite::Sprite.  Should fix problems with white banners and garbage on videos.
add missing nextrow character for options rows
make a note about DirectX 9 in the NSIS installer script
(I'm not sure how to fix it just yet)
DX8->DX9 in the rarely updated Manual
fix really awkward positioning of this line (was using spaces instead of tabs)
