Chrome extension: Easier setup

[jancborchardt]

After you installed the Chrome extension and want to Poche your first link, you’re faced with a popover saying:

please setup the extension by going in the Options menu.

With no other help. Easier would be if the content of the options menu (the web address input) would simply be in the popover itself.

Temporarily, I'll think I will do a simple link to the options page.

Let's see what @jogaulupeau thinks of it.
