Changes (by teor):

 * version:   => Tor: 0.2.6.1-alpha


Comment:

 OK, so from reading the code, if the network has no exits:

 The following circuits should still be built, and are internal:
 * Hidden Service Circuits (Server, Client, Introduction Point)
 * Socks Proxy Circuits (when connected to HSs)

 The following circuits should be built, but aren't currently configured as
 internal:
 * Circuit Build Timeout Circuits
 We could conditionally configure these as internal if there are no exits
 in the consensus.

 The following circuits can never be built (and we shouldn't try, as it
 produces lots of errors):
 * Exit Circuits
 * Socks Proxy Circuits (when connected to Exits)
