Align with changes in lingua-franca master

[edwardalee]

This PR aligns the grammar with lingua-franca master so that the VS Code extension in lingua-franca will work smoothly with reactor-uc.

• changes the grammar so that forever and never are Time objects rather than Literal.
• Requires a maxwait body to appear before a deadline (for compatibility with lingua-franca. (Note that it would be better to allow either order, but that will have to be another PR).

There are a few other small changes that start the process of making files that should be identical to those in lingua-franca actually identical. Hopefully, we can eventually eliminate the duplication.
