Setting up Nuxeo Drive on the desktop after downloading it from the Nuxeo server

User goes to the Home/ Nuxeo Drive section and finds a link on the first tab of this area to download Nuxeo Drive (he can choose a link for mac os or for windows, and maybe depending on the versions 32-64bits, ....). As a first iteration of this user story, all bundles are available, a refinement will be to show only the adapated one, from the user-agent.

Then he downloads the package (MSI for windows, DMG for mac osx)and run the setup. A popup asks him the server URL, the username and password (another user story will be done in the future to make this more user-friendly, with auto-config).
