Plugin: Replicate value of $HOME in users .env file so that foreman works correctly on windows.
Plugin: Set -Xmx128M and removed -XX:+UseCompressedOops from $JAVA_OPTS. 128MB should be enough for most local testing, and compressedOops only works on 64bit Java. This option is managed independently on Heroku.
Plugin: Switch from using jar tool to using native ruby unzip to explode war file. This works even when java is fubar and is more reliable on windows.
Plugin: Replaced using system to call heroku commands with direct api calls. Is faster this way and there are more opportunities to detect and resolve errors.
