Cohesive Editor Support

The main purpose of this project is to make the text-editors of coala more robust and active. This will be done through ensuring that the plugins are up-to-date with proper tests and continuous integration, to make maintenance more simplified for contributors in the future. This project will be completed through the use of several open-source tools. Further, the completion of this project will lead to other developers having the freedom to use coala in their favourite text editors. The ease of usage in different text editors may also help potentially serve as a way to popularize coala.
