grafana_com: changed name of oauth grafana_net integration (old settings names still work), and updated login button look, closes #8415

remove dev.ini reference as it seems not working anymore.

Please let me know if this changed in a more recent version of Grafana, but when using 4.2.0 the manual install directions were off a little (there was no `data/plugins` directory, only a `plugins` directory).
