Replace obsoleted -mem parameter with -J-Xmx512m

Apparently `sbt-native-packager` removed the `-mem` parameter with sbt/sbt-native-packager@62362c2377 - so if you look in a subscriptions-box, you see this in `/subscriptions/stdout.log`: ``` !! WARNING !! -mem option is ignored. Please use -J-Xmx and -J-Xms ``` sbt/sbt-native-packager#82 (comment)
