EXP-648 FIX As a developer, I want to be able to specify param blocks that use Multiple<LLUIImage> for a sequence of images

Factored out param block data classes so that specialized param block types, such as LLUIImage, LLFontGL, LLRect, etc. can be stored in a Multiple<T> context
Converted loading_indicator to take image sequence from XUI
deprecated name-value pairs for LLUIColor values, and put them in colors.xml
