Hide mnemonic by default during restore

[ascartabelli]

Summary

During the restore phase, which soon will be triggered when a mnemonic change is detected, we show the mnemonic we're about to restore.

We should consider the possibility of hiding it by default, and add a control to toggle its visibility, so that the user can confirm he's in a safe place where no one is looking at his screen.

Also @laremas, while discussing this issue with @ZER0 we both agreed that the current design makes the eye follow columns, instead of rows.

Can you think about it? Only thing that comes to mind right now would be having alternating row colours, to force the eye to follow rows.

This is common for a lot of wallets, i would not make it similar to a table. I know that eyes follow columns (in our side of the world), but we are also showing the number of the words before them. Do we really wanna change this component?

It's not that we really want to change: was just a thing to consider as it came up.
