RFR: JDK-8217331: Problems when space in application name

[Andy Herrick]

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).

The webrev includes removal of the APP_FS_NAME DeployParam, and 
enhanced  checking of the given application name so APP_NAME parameter 
can be safely used in all cases.
