A couple of minor updates to accomodate the change to Xcode 8.3.

Xcode 8.3 comes with a few new depreciation warnings that mar the otherwise clean compilation. This update removes the reason for these warnings.

In addition, a dummy COpenSsl was added to SwiftfireConsole to prevent linking problems.

Lastly the installation procedure was updated to address a new problem in SwifterCore where the new Xcode release was unable to locate the module.modulemap file for CAsl.
