Add a help button

[laurent22]

It would be interesting to add a menu or a simple "Help" button on the mobile version of Joplin (we currently have access to the website in "More information" but it's not very clear for users). We could add a "Help" button redirecting users to a choice between the forum, discord and documentation, for example.

We still need to decide where this button should be though.

I have a few possible proposals for this:

Proposal no. 1: The add note button with the + sign (shown below) is consistent across all pages, and is easy to access everywhere. Therefore, we could possibly add another help button somewhere around it (ex. on top of it) that can redirect users to where it's needed. As shown below, having the button where I've drawn is a possible example that will be easy for all users to find and access it.

Proposal no. 2: Just like the "Welcome!" notebook is defaulted on every app (shown below), we could also possibly make a default notebook for Help, with all the relevant resources in there.

Proposal no. 3: The final, most intuitive place I would assume to put it would be the navigation bar on the top, but I'm not sure how feasible it would be to do that and while also not making it look cluttered.
