[Complete] Add xwidget layer

[tuhdo]

Add xwdiget layer that configures xwidget-browser to behave more like a
normal browser. In the future, anything related to xwidget - aside from
the browser - should be put here. Hence the name "xwidget".

I would like to state that I love how fast this community moves! <3 I am on OSX so can't test right now but OMG this is so great

[CestDiego]

I do believe though that for OSS sake, we should think in Shareability of configuration so many more people can use this and extend this, this way it could be less of an spacemacs-layer only type, to a MELPA package that everyone can install and we can decide to use it as a Spacemacs layer too, kinda like what Spaceline became

Vimium - good surce of inspiration for the future work 😉

[tuhdo]

I will try shorter implementation soon, without involving macro.

It's done now. The commit can be reviewed and merged.

Sure I would like it that way. But let it be mature in here first, then we can expand it into a full package. And I think, in the future these features will be added to core Emacs eventually.

My point was that by getting exposure from all the people wanting to try it out it could drive even more collaboration, it's very valid if it matures inside our community as well, just wanted to put it out there that we should be thinking about making this shareable in the future and this to drive the design decisions (not tying it too much to spacemacs-only helper functions, etc).

If we don't take that in mind, we are expecting a major rewrite in the future, which we might have to do anyway. In any case I'm happy this is being even done <3 thanks @tuhdo . I'll try to help out when I get my hands on a linux computer again T_T or if I figure out how to do this in OSX when I get a personal laptop

Now I added support for properly copy text from Xwidget browser. Here is a comparison:

• Before:

• After:

@CestDiego this layer does not depend anything in Spacemacs, but Xwidget itself. Sure, I will make a package out of it soon, when it works decentl

[tuhdo]

As @CestDiego suggested, I think it's fine to make a separate package now. I will do it soon. In the meantime, feel free to try this layer.

[tuhdo]

Done. The package is here: https://github.com/tuhdo/xwidgete

[CestDiego]

Thank you @tuhdo for all this effort! :D

Seems there are some unresolved security issues with libgtkwebkit, I did not check it though. We should add a warning in the README.
