Reorganize module loading.

We now use webpack instead of SystemJS, effectively bundling modules
into one file (plus commons chunks) for every entry point.  This results
in a much smaller extension size (almost half).  Furthermore we use
yarn/npm even for extension run-time dependencies.  This relieves us
from manually vendoring and building dependencies.  It's also easier to
understand for new developers familiar with node.

-It obeys the `--color` and `--no-color` CLI flags.
 
+## API
 
-## CLI
+Returns an `object`, or `false` if color is not supported.
 
-```sh
-$ npm install --global supports-color
-```
+The returned object specifies a level of support for color through a `.level` property and a corresponding flag:
 
-```
-$ supports-color --help
+- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
+- `.level = 2` and `.has256 = true`: 256 color support
+- `.level = 3` and `.has16m = true`: 16 million (truecolor) support
 
-  Usage
-    supports-color
 
-  Exits with code 0 if color is supported and 1 if not
-```
+## Info
+
+It obeys the `--color` and `--no-color` CLI flags.
+
+For situations where using `--color` is not possible, add an environment variable `FORCE_COLOR` with any value to force color. Trumps `--no-color`.
+
+Explicit 256/truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
