DWT Linux supports D2

[Jacob Carlborg]

I finished (or mostly) porting DWT linux to D2. The browser package is 
exclude from the build. Most of the snippets build and (I think) most of 
them run. Please create a ticket for any compile time or run time errors.

Build base and SWT: "rake base swt"
Build SWT snippets: "rake swtsnippets"
Library dependencies: http://dsource.org/projects/dwt/wiki/ImportLibraries
