New methods don't call start automatically. This is important when
filters, etc are setup after a replication is created in a multithreaded
environment. This fixes an issue where ti_touchdb would sync once at
startup but never again.
Merge pull request #58 from ijcd/fix-replication-using-undeprecated-methods

Hey Ian -

Thanks for the fix for the deprecated methods.  I am using my fork of couchbase-lite-ios because there was a time earlier in the year when I was discovering issues and making improvements to that library based on the ti_touchdb module code and unit tests.  Now that Couchbase Lite is in beta, this is less important than it once was.
