I've got a ant run task on my laptop I can check in when I get home.  
That browser.bat is made for the installer and must have the libraries 
laid out as the installer does.  Won't help you with running from svn.  
Run task is typical ant task with these args:

<property name="runarg0" value="-Xmx1200m"/>
<property name="runarg1" value="-Dsun.java2d.noddraw=true"/>
<property name="runarg2" 
value="-Djava.library.path="./natives/${os.name}/${os.arch}"" />


you'll need lib, jars and apps/browser/jars on the classpath.
