Added commit from internal repo, housekeeping.

[mparker17]

Problem / motivation

There was a commit on our internal repo (45a7fe1) that had not been pushed here but was being used in our environments, so I pushed it to CWRC's fork.

I also:

• Made the module conform to Drupal coding and documentation standards.
• Removed unused variables.
• Organized .module file, grouping together related functions.
• Added an empty gitignore (Github recommends every repo have one of these even if they are empty).
• Added Github issue and pull request templates (I used the PR template for this pull request!)
• Added Contributing Guidelines (Github recommends every repo have one of these)

Proposed resolution

Merge in the changes on CWRC's master branch (i.e.: this pull request)

Remaining tasks

• Code review
• Commit

User interface changes

None.

API changes

None.

Data model changes

None.
