1.3.0

Enhancements

• New --verify option to swiftenv install to verify binary snapshots using
  GPG. This option expects that GPG is setup and configured to accept the Swift
  master keys. Verify can be forced with the environment variable
  SWIFTENV_VERIFY.
• Added local cache for Swift binaries for 3.0.2, 3.1, 3.1.1.
• swiftenv install will now resume any failed downloads instead of restarting
  the download process when restarting an install.
• swiftenv install --verbose will now include verbose build output while
  compiling swift.
• Adds build instructions for Swift 3.0, 3.0.1, 3.0.2, 3.1, 3.1.1, 3.0-dev,
  3.1-dev and 4.0-dev.
• When building Swift from source, swiftenv will download tarballs instead of
  git cloning the repository resulting in faster download speed.
• Adds support for Fish 2.6.
