* A few small fixes:
- Add missing spaces after commas;
- Add URL syntax around will62794/tlaplus_animation;
- Add missing URLs to module overrides;
- "page 178ff" -> "page 178"
* Add (original) contributor to Functions.tla
* Add contributors
* Add missing modules to README.md
* Sort modules alphabetically; Right-align 'Name' column; Center-align 'module override?' column;
* Fix Combinatorics.tla module description
* Change module descriptions and add operator examples
