Add "New app" as a "Transparency" score for new wallets with a short track record

[saivann]

There seems to be a few interesting wallets (Aegis, Breadwallet, Ciphrex) which may be good choices for the user. However, many of them have been released only more recently.

This pull request adds a "Transparency" score text which warns the user that such wallets still don't have a very long track record, in order to find a good compromise that would allow us to list them while being transparent about the few public testing / review these wallets may have received yet.

I like this idea. I suggest we change the second sentence from:

However, this wallet still has a short track record and few public feedback, testing and reviews.

To:

However, this wallet has not been tested and publicly reviewed by a significant number of people.

This removes the metaphor/colloquialism "short track record" which may not be clear to certain non-native English speakers and so should allow for a smoother translation.

It also removes the time dependency here: in my opinion, it's the lack of reviews, not the age of the wallet, that matters most---so by not mentioning time, we can now apply this warning even to older wallets. (I think one of the wallets mentioned in the OP said it was over a year old---yet I had never heard of it.)

@harding Thanks! I think your version is indeed much better.
