Maven Restructure

1) Move Waffle Parent pom and files up one directory to root of JNA
folder
2) Move Waffle Demo Parent pom and files up one directory to root of
Demo folder
3) Flag all src/git properties location in each pom.  Previously src was
format location.  Now used for additional setting thus src naming.
4) Copy license txt into demo folder.  Due to defect in licenser plugin
trying to guess location of project setup, not copying there results in
inability to build from any pom.  This resolves that.
5) Switched next version to 1.7.2 in preparation to push a release under
this structure.
