Previously `sscanf` is used in decoding the url-encoded html document.
But `sscanf` is quite expensive. Loading a larger document (~800KiB) has
a noticeable delay.
And mshtml is giving the third argument to `sscanf` a `char*` when it
should be an `int*`. It is very problematic.
This commit replaces them with our own hex decoding function.

Closes#105Fixes#52
Added missing linked libraries to edge backend.
I also kept the pragmas, if someone want to build the backends separately, so they do not have to supply link library flags to msvc.
Previously the backend would define some functions differently and had some functions missing.
Now that all of the backends use the same webview.h header, we can make sure that all the functions needed are there.
