Motivation for this change

Kent utilities are a very versatile and fast suite of bioinformatic tools that has been available for a long time. It has some very nice tools to optimize for visualization of big data.

Things done

I have put the mit license, however some of these tools are not allowed to be used outside non-profit organizations. My understanding of nixpkgs is that it is completely non-profit.

For lib, inc and utils the MIT wording has been used:

• https://github.com/ucscGenomeBrowser/kent/blob/master/src/lib/LICENSE
• https://github.com/ucscGenomeBrowser/kent/blob/master/src/inc/LICENSE
• https://github.com/ucscGenomeBrowser/kent/blob/master/src/utils/LICENSE

The licenses where there are exceptions from the mit license says this:

License hereby is granted for personal, academic and non-profit purposes

• https://github.com/ucscGenomeBrowser/kent/blob/master/src/lib/README#L9
• https://github.com/ucscGenomeBrowser/kent/blob/master/src/jkOwnLib/README

Should I choose something else than mit?

It is possible to build the utility suite without these libraries, but I am also working on adding ensembl-vep, where these libraries are required. Since there also are commercial binaries in nixpkgs, I don't think this should be a problem, but I am not a lawyer ..

I really hope these tools can be added to nixpkgs.
