Grails command update

Grails is quite memory hungry. To save time I often update the  grails batch file to give more memory on startup, so you don't get those outOfMemory errors, such as

java.lang.OutOfMemoryError: PermGen space

%GRAILS_HOME%\bin\startGrails.bat 

to include the following line  (near bottem , e.g. on line 135 of grails1.3.5 startGrails.bat)

set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m -XX:MaxPermSize=512m
