Travis CI Pro fix needs to be backported for travis-encrypt to work

[kaizhu256]

need to bump travis-ci dependency in package.json to include the following patch:

pwmckenna/node-travis-ci@7d1eb44#diff-9ca2b835b96fd3a57aac1782b9df9e7c

specifically:
lib/travis-ci.js

•        name: 'Travis Pro',
  

•        name: 'Travis CI Pro',

somehow let this slip. the version was set to ^2.0.0, so hopefully it picked up the 2.0.3 release, but I just bumped it as part of the 1.1.1 release. thanks!
