Travis Browser badge

I'm running several selenium tests in different browsers directly on travis CI.
e.g. in this project: https://github.com/christian-draeger/basic-selenium-project

therefore it would be awesome to have the browser badges available for travis CI

it would be nice if one could do something like this:
`http://badges.herokuapp.com/travis/christian-draeger/basic-selenium-project?env=BROWSER=firefox&env=BROWSER=iexplore`

or at least setting it hisself:

`http://badges.herokuapp.com/travis/christian-draeger/basic-selenium-project?env=FOO=bar&logo=firefox`

and get the following result
