Google Chrome support for automated webtests

[jkokocha]

When running automated tests, the user should be able to choose if they want to run the tests using Firefox och Google Chrome. At the time of writing this, the tests only run on Firefox, which may result in certain features not working on Google Chrome going unnoticed.

Requirements:

• When running tests, there should be a choice between if you want to run them using Chrome or Firefox
• Add Google Chrome to dependencies
• Add information about chromedriver in readme
• Edit the CI pipeline so that all Selenium Webtests run on both Chrome and Firefox
