Add connection support for SQLAnywhere12 and 11

Support for the old version (4?) has been removed.

12 and 11 are currently the only active versions of SQLAnywhere
http://www.sybase.com/products/databasemanagement/sqlanywhere?htab=Technical+Info&vtab=End+of+Life&hid=79519&vid=79601

I'm not against older versions being added/readded, but 11 and 12 are the
only versions I have access to.
