Implement Rollup and minor fixes

Minor fixes and additions
- Found a missing / in the <strong> tag in the french translations. I've
added it.
- Fixed a missing capital letter in the English translations
- Added an editorconfig to standardize the "format document" of editors
such as VSCode

Rollup has various advantages but to list a few
- Small bundle sizes for both Node and Browser
- Treeshakeable, this is primarily awesome for browsers because there is
no reason to load in languages that are not being used. Instead by the
power of treeshaking only 1 language gets bundled by webpack.
- Single tsconfig file that defines how the lib is coded, not how its
build
- Automatically running of Terser for minification and compression
- If you need any convincing that it's a good thing to use, it's also
being used by the main React library and maaaany other packages.
- Exported the drawLocales function as both a default export and a named
export
