DWT2 now looks working on Windows (except Text widget doesn't support UTF-8)

[Denis Shelomovskij]

About month ago I fixed some DWT2 bugs, but DWT maintainers just have no 
time to pull changes to the main repo. Changes are in my (denis_sh) 
commits descriptions:
https://bitbucket.org/denis_sh/patching-dwt2

Short changes description:
1. DWT2 now works on Linux32 with Phobos/D2 as bad as with Tango/D1 (not 
worse): lots of segfaults when printing and text editing and other bugs.
2. It looks working stable on Windows except Text widget sill doesn't 
support UTF-8 (yes, StyledText and it's friend now support it).
3. It now have compilable and right snippets.
