there won't always be a space after sasl in CAP ACK

see #45

I can see how this happened; if you look at the CAP ACK output from the test server in test.js:

raw:  { prefix: 'irc.dollyfish.net.nz',
  server: 'irc.dollyfish.net.nz',
  command: 'CAP',
  rawCommand: 'CAP',
  commandType: 'normal',
  args: [ '*', 'ACK', 'sasl ' ] }

note, the space after sasl in args

but if we point it at a different ircd...

raw:  { prefix: 'irc.darwin.network',
  server: 'irc.darwin.network',
  command: 'CAP',
  rawCommand: 'CAP',
  commandType: 'normal',
  args: [ '*', 'ACK', 'sasl' ] }

additionally, CAP ACK lines look like this when you CAP REQ more than just SASL:

:server CAP * ACK :account-notify sasl multi-prefix

good catch, I think this is fine. @jesopo can I get a sign off from you as per https://github.com/matrix-org/matrix-appservice-irc/blob/master/CONTRIBUTING.md#making-pull-requests?

(Sorry it's not clear about that in the README, E_TOOMANYPROJECTS)
