RFR: JDK-8191709 : javapackager detects WiX 3.10 as 3.1 and fails to use WiX 3.6+ compatible code

[Alexander Matveev]

Please review the jpackage fix for bug [1] at [2].

This is a fix for the JDK-8200758-branch branch of the open sandbox 
repository (jpackage).

- Problem was in how we compare versions. We used to compare it as float 
number, so 3.10 -> 3.1 which was less then 3.6.
- Fixed by comparing major and minor version separately.
- Fixed minor spelling error in resources.
