Readme should be reorganized

[stleary]

The readme has too much unrelated content.
These sections should remain:
Header (image, title, Maven links)
Overview
If you would like to contribute
Build instructions

These sections should be removed. Leave a copy of the section header, but add a line that links to the new .md file. See the If you would like to contribute section for an example of how to do this.
Notes: Extract content, move to a new NOTES.md file
Files: Extract content, move to a new FILES.md file
Release History: Extract content, move to a new RELEASES.md file

Hello, can you assign me this issue? Would love to work on it.

@Ronqn Sure go ahead. The main readme should stay in the root directory, I think. But if you decide to put the new files and the other existing contributions file into a docs directory, that would be fine.
