* Updating documentation and npm packages
- The webpack 3.10 was too old, as webpack-cli and webpack-command, required dependencies for building, need 4.x.x or 4.4.0 respectively.
- `npm-check-updates` (`npm t -g npm-check-updates`) run with `ncu -u` auto-bumped xterm.js to 3.6.0, and webpack to 4.16.5. Unfortunately this also reordered the file, so those changes aren't obvious.
- I also added webpack-cli as an explicit dependency.
- Updates to the readme to detail putting together a build environment.
* Noting that the package should be for sideloading
For dev, and non-published packages, the sideloading option is best.
* Adding dev StoreAssociation XML file for dev building.
* Cleaning up the packaging instructions.
* Changed instruction from rename to copy.
- Copy will not try to clobber the working directory of the template
file.
* Bumping xterm to 3.6.0, adding notes on installing built packages
