Url format was changed for Sventon 2.x, so integration is not working. There
should be added two option for Repository browser (Sventon 1.x and Sventon 2.x).
More generic solution will be to add Generic Browser and typing full url for
browser, only revision should be parametrized.

New url format is:
http://SERVER/APP/repos/PROJECT/info?revision=REVISION

while old url format was:
http://SERVER/APP/revinfo.svn?name=PROJECT&revision=REVISION
