Create build/package/sign script and resources for Mac

[PropGit]

Create a script to build, package, and digitally sign for Mac.

Add to repo.

This is required as a related step of Issue #33.

[PropGit]

Building script. Tested and debugged up to signing the package. Has output and timestamp problem.

[PropGit]

The new build script is working and we can now sign and package for the Mac as of commit b8c8ba.

See README.md for configuration and building/signing/packaging instructions for Mac.

[PropGit]

The script is executed from within the package/ subfolder like so:

$ ./mac_app_sign_and_package.sh -a "BlocklyPropClient" -v 0.5.1 -r -f -d

and the output should look something like this:

----------------RECIPE----------------
* Processing target: "../dist/BlocklyPropClient.app"
* As build version: "0.5.1"
* Using application identity: "Developer ID Application"
* Using installer identity: "Developer ID Installer"
* Restart required after installation
* FTDI kext WILL BE installed by this package

Validating developer identity certificates...
  Found Application Identity: "Developer ID Application"
  Found Installer Identity: "Developer ID Installer"

Code signing the application bundle: ../dist/BlocklyPropClient.app with identity: "Developer ID Application"
../dist/BlocklyPropClient.app: signed bundle with Mach-O thin (x86_64) [BlocklyPropClient]

Validating application signature...
  Verified ../dist/BlocklyPropClient.app signature

Package’s CFBundleIdentifiers will be set for deployment

Found FTDI USB Serial Driver kext
