Studio level100: toolbox level now includes blocks that take blocks as input parameters

New blocks needed for this level:
moveDistanceParams, showTitleScreenParams, saySpriteParams, waitParams, setScoreText

The first four are created with shared functions that initialize both the non-params and the params version of the same block. setScoreText is an entirely new block that can be used instead of the simplified incrementScore block.

Also: added a new Text category and a few blocks to the Loops and Math categories.

This level is now essentially complete. You can create some sophisticated "apps" now. It is for advanced grade levels - like the Artist levels that use functions, variables, etc.
