for #1177: add a <a> element on page title to support link to home

[parmentelat]

hey

as a first step towards #1177 I had been playing with this approach
rationale being the home icon in the header, which at first I had taken as a hint towards going back to home page

I could maybe also add a shortcut as per your suggestion but I do not yet feel comfortable messing about in this area

let me know what you think

Ah interesting, just pulled this down locally to play with it:

It's a good start! But I think my hesitation is that:

• its not super clear why the header is blue now
• clicking it will immediately clear your local state, possibly wiping out any progress you might have!

so I worry about people accidentally clicking it. It's also a bit of an odd visual design paradigm to have a link thats not underlined.

Its super easy to add another icon in that bottom bar. Just edit this file and add a new entry:

learnGitBranching/src/js/react_views/MainHelperBarView.jsx

Line 70 in e12ed5a

newPageLink: true,

Use the icon classname here:
https://fontawesome.com/icons/broom?f=classic&s=solid

and then execute something like this to perform the reset:

learnGitBranching/src/js/react_views/CommandsHelperBarView.jsx

Lines 37 to 40 in e12ed5a

	text: intl.str('command-helper-bar-reset'),
	onClick: function() {
	this.fireCommand('reset');
	}.bind(this),
