Glimmer DSL for SWT 0.6.1 Cleaning Windows

Glimmer DSL for SWT 0.6.1 has been released. Glimmer finally cleans up its act on Windows, making scaffolding work in CMD, Powershell, and Git Bash without the need for RVM on Ubuntu Windows Subsystem for Linux. Also, Girb is finally fixed on Windows. One other issue that was discovered in relation to Windows is jar-dependencies not getting packaged in Glimmer apps (was not an issue on the Mac). Also, fixed.

Here are all the changes:

- Lock JARs task for jar-dependencies as part of packaging

- Add 'vendor' to require_paths for custom shell gem

- Add Windows icon to scaffold

- Generate scaffolded app/custom-shell-gem gemspec as part of packaging (useful for jar-dependencies)

- Support a package:native type option for specifying native type

- Add a preferences menu for Windows (since it does not have one out of the box)

- Fix app scaffold on Windows by having it generate jeweler gem first (to have gemspec for jar-dependencies)

- Fix girb for Windows

Happy Glimmering!
