Update all published README.md files.

[pixelzoom]

Now that TS is in common code, all sims require a compilation step before they can be run. This is not currently reflected in README.md files for published sims.

When updating README.md files, be sure to take #1136 into consideration. Prototypes have a version >= 1.X.X, but should not have a published README.md.

I updated the template but thought it would be wise to request review before applying it to 100+ repos:

The proposed changes in #1157 (comment) look OK to me.

@marlitas and I updated all the readmes as described in the preceding comments. @pixelzoom would you like to review?

I spot-checked a few README.md files. Looks good. Closing.
