Minor: version info of extension

One little request: in order to see what extension version the users have, it would be nice to have it updated on a new release. 
Atm, https://chromewebstore.google.com/detail/aurelia-inspector/gnoofhkmbmehifoogkgcfiaafladchmg just mentions v1.0.0 - which it could be just the current one, but it's not visible at the releases tab on this project :)
