Include main-class name in jar name or generate multiple jars

[dainkaplan]

Currently if your project has multiple main classes, you must select one when running one-jar, but the resultant jar file always has the same name. It would be nice to either (a) automatically include the main class's name in the jar file name, or generate a one-jar for each main class that exists.

is this a really dumb suggestion or did someone just neglect to look into?
