Enable no-wgl and include EGL DLLc in cargo packager

[wusyong]

While cargo run on Windows works fine, it will need several DLLs to make the actual binary work.
In the final package, following DLL sources should be included:

Its mostly libgstreamer right or are there any other deps that are needed?

Nevermind, I see that there is also MSVC stuff involved. Ill take a look.

We will use cargo packager in the future. Probably worth looking into it to see if it has option to include custom dlls.

Ill check. My first go to was to just add a build.rs file that uses pkg-config but I am sure that cargo packager has its own stuff for that.

edit: I took a look and it looks as though they use WiX. It would be easier to have a build.rs rather than having to create a wix bootstrap program.

Rename the issue because it's WGL by default now. But since ANGLE is more stable, it's still better to enable it when we build with cargo packager in the future.

I'll handle this in #85
