License files for all common phetsims repos should match

[samreid]

All of phetsims common code repos should have MIT licensing. We'll use GitHub's default MIT license formatting. I generated a sample license file using GitHub "initialize with MIT license" here: https://github.com/samreid/testmitlicense/blob/master/LICENSE

[samreid]

Actually I think the copyright holder should be "University of Colorado Boulder", not "PhET Interactive Simulations". I'll update the license files.

Assigned to @samreid to check on this and see if anything's left to do.

I wrote a script (see commit above) that iterates over all active repos and prints the 1st line of LICENSE. Output follows:

Several problems here:

1. babel has no LICENSE file (even though the README links to it)
2. beaker's LICENSE file looks like a copy/paste error
3. chains is LGPL. Should be GPL (if a sim) or MIT (if common code)
4. the text for phet-metacog/LICENSE is wrong
5. rutherford-scattering is the wrong license, should be GPL but it is LGPL
6. shred is missing its LICENSE file. If common code, it should be MIT

[samreid]

I fixed two items above and created issues for the remaining four issues. An additional step for this issue will be to make sure the formatting/text/everything matches up for all LICENSE files of the same type. I do not have plans to work on that at the moment, and am hence unassigning the issue. Others feel free to take a look if you wish.

I'm going to close this issue because the remaining repos that don't have licenses (babel, shred) are covered by issues specific to those repositories.
