232 & 317: Create contribution guidelines, remove .vscode directory

[ejwoods]

Description

Create contribution guidelines

• created .github/docs/CONTRIBUTING.md
  • this file establishes guidelines for contributing to the Linkta repository. The primary use of this file currently is to describe necessary vscode workspace settings. In the future, it can be expanded to describe the process of making Open Source contributions to the project.

Remove .vscode directory

• removed .vscode/settings.json
  • this directory is already in the gitignore so I'm not certain how it ended up in the repo. I expect that when this PR is merged, any open PRs from branches tracking the directory will have a conflict; so as long as they also remove it, we should be able to prevent it from getting back in.

Fixes #232, #317
