Update manifest aren't used for Chrome anymore, but only for Opera devbuilds.
However, specifying an update_url prevents upload to the CWS. So we have to give
up on updates, if we want to get rid of seperate devuilds for Opera. However,

sitescripts/extensions/bin/createNightlies.py:249: manifestPath =
os.path.join(baseDir, "update.rdf")
Update manifests are also not used anymore for Firefox. And I had to touch this
code anyway, as with just the branch above removed, it would generate an
update.rdf for Chrome otherwise.

For reference, the web store URLs are hard-coded on adblockplus.org meanwhile.
And the mechanism here is only used anymore for extensions hosted on our server.
