Add GitHub wizard to Gerrit Top-Menu.

Allows a user to come back to the GitHub import
wizard steps (Profile, Repositories, Pull Requests)
using the Gerrit Top-Menu under the Entry "GitHub".

GitHub wizard can be run multiple times and always
works in differential way, there is no harm then
in allowing the user to come back for updating its
keys or importing extra repositories or pull requests.
