Updated to TCAL build 174. (Note: I did NOT update the players.)
The 'whitespaceCollapse' property in ICharacterFormat is now spelled 'whiteSpaceCollapse' to match the FXG 1.0 spec. (However, the corresponding enum class has not yet been renamed from WhitespaceCollapse to WhiteSpaceCollapse.)
The [Style] metadata in Flex has been updated to match this spelling.
