Add yoga support. Fixes #67

[kusti8]

This is the PR that fixes #67.

It can't be merged right away because I still need libui support for GtkFixed and their equivalents on Windows and Mac, as well as sizing. Once that is done, which I'm going to work on now, then I can merge this. The API shouldn't change too much. If you're interested, I've added uiFixedAppend and uiFixedMove, as well as uiSize and uiSetSize. These are what need to be added to Windows and Mac and can be found on my libui and libui-node fork.

This currently supports full yoga layout, as far as I've tested. Meaning nested Views and all styling works. One thing that doesn't work is having a container such as a box as a child. You can't really mix yoga and stretchy layout.

To test:

• Clone my libui fork and checkout the alpha3.5 fork (because libui-node currently only supports alpha3.5). This has my changes.
• cd libui && mkdir build && cd build && cmake .. && make
• Clone my libui-node fork
• Copy the header files in libui into libui-node root directory and the build/out/*.so files into the libui-node root directory also
• cd libui-node && npm i
• sudo npm link
• Clone proton-native and checkout the yoga branch
• npm link libui-node
• npm i
• npm run demo

Currently, I need to merge a component into libui that allows fixed positioning, but I need to rewrite the GTK version, and its taking some research and time to do that.

What would be the stuffs to investigate with Gtk for this to progress, I have a long experience with it, may I help?
