remark-lint (#54)

* Install `remark-cli` and `remark-preset-lint-arcticicestudio` NPM pkgs.

Installed remark-lint (1) through `remark-cli` (2) using the
`remark-preset-lint-arcticicestudio` (3) preset that implements the
"Arctic ice Studio" Markdown Style Guide (4).

Also updated the Git ignore pattern to handle "Node.js" data.

* Implement remark config and ignore pattern file

Created the main remark (1) configuration file and initially set up the
`remark-preset-lint-arcticicestudio` (2) preset.
Also added the `.remarkignore` file with to define ignore pattern.

* Implement NPM script/task to lint Markdown files

The NPM scripts/tasks allow to run the Markdown linting separately and
as well as running the all `lint` task together.

Also added the `npm-run-all` package that simplifies the paralell and
serial execution of multiple NPM scripts/tasks including name wildcard
support.
