Release dwtlib v3 for use with DMD 2.074.0

[JamesD via Digitalmars-d-dwt]

dwtlib - DUB package for the D Widget Toolkit

https://code.dlang.org/packages/dwtlib

DWT is a library for creating cross-platform GUI applications.
It's a port of the SWT Java library from Eclipse.
WORKING and tested on:

	- Windows 10 Home  32-bit and 64-bit
	- Ubuntu 16.04 LTS 32-bit and 64-bit
	- DMD32 D Compiler v2.074.0, DUB version 1.3.0
	
     DWT cloned from Github is NOT compatable with DMD v2.074.0 
"as-is"
     There is some issue with DMD v2.074.0 writing *.di files
     When compiling, DMD imports the *.di files and fails with 
warnings
     dwtlib v3.0.0 imports the *.d source files versus the *.di 
files

Todo
     Sent a pull request to Jacob Carlborg
     Checking if he wants to modify DWT as I've done with dwtlib
     The end state would be the official DWT repository as a dub 
package on code.dlang.org
     Then I would remove dwtlib in favor of the official DWT dub 
package
     I sent a pull request for the first step in getting there
