Fixed the imgui project so we can do a dev (incremental) build and a distribution build

Start prepping for dev SystemJS build

Test rendering some stuff finally!

Do all the building with the typescript rollup plugin (and ignore the cache folder for that). Include the node builtins plugin, and update imgui-js to fix the bad module references to imgui-js

Try using rollup with plain es2015 modules (commonjs for bind-imgui)

Try rollup (does it combine files?)

Very simple setup with systemjs. Doesn't load modules, doesn't rollup yet

Actually call init() on window load

Test index.html and main.ts file just to load up ImGui. May have to switch the module setup on imgui-js to not use systemjs, and go with something browserify-compatible

Added emsdk and imgui-js as modules (imgui-js comes with my fixes from the new git.mhack.io)

Start work on implementing the 7gui exercises with typescript and a webgl IMGUI
