add MessageFilter to selectively block window message #183

This PR introduces BREANKING changes described below;

add MessageFilter to selectively block window message Blocking every window message blocks intentional user actions like minimizing, closing(Alt-F4 doesn't work either), resizing, etc. This commit fixes that kind of problem by providing bitflag interface to block certain predefined range of window messages. To block every messages like before, you can return MessageFilter::all() on set_message_filter().

This PR fixes #182.

Thank you for your contribution! 🙏 Please allow me a bit of time to thoroughly review this, but I like what I've seen so far.

In addition to your change requests, I made MessageFilter::is_blocking() pub(crate), because it would not be used in user code.

Test for only MessageFilter::WindowControl is added to the test hook, because harness itself doesn't seems to handle any input.

The font is NeoDunggeunmo Code. It's one of a few programming fonts that natively supports korean glyphs, and because of its bitmap appearance and square sizing it matches very well with unifont fallback.
