Add file association with .jar #112

Running executable JARs requires calling java.exe -jar "%1", but when selecting the java.exe in explorer, it uses java.exe "%1", which fails.

i suggest adding something like:

manifests:

{
    [ ... ]
    "postinstall" = [ 'echo "In order to associate jar files, run sudo associate-javaw.bat"' ],
    [ ... ]
}

/scripts/associate-javaw.bat:

@echo off
assoc scoop-javaw="%JAVA_HOME%\bin\javaw.exe" -jar "%1";
assoc .jar=scoop-javaw
