Add basic support for dwmapi and ANIMATIONINFO

[daniel-abramov]

This pull request consists of several commits:

• Adds support of DmwGetWindowAttribute() function used for getting some useful windows attributes (and it also adds required constants that are usually passed to this function).
• Adds ANIMATIONINFO structure to the winuser module along with some constants that are usually used in conjunction with ANIMATIONINFO structure and SystemParametersInfo() function.

P.S.: The previous pull requested was not accepted for a long time, due to that it was not in a 'mergeable' state today as some other commits were pushed to the master branch meanwhile. I pulled the changes (with --rebase enabled), so now it should work.

This PR will need to be updated for the winapi 0.3 new world order. #316

Hi @retep998 , I updated the pull request, please have a look. Now it should work (passes CI tests/builds).

I also have one question. Did I get it right that the current master branch is not in a usable state? I tried to use the new master branch for my project and now it does not work as everything inside lib/* is not accessible anymore, so I'm not able to call gdi32 functions for instance.

@application-developer-DA winapi 0.3 is a rather significant overhaul and it's not done yet so there's a lot of code that is inaccessible at the moment.
