Rename Organizations to DIGITAL IDENTITIES in the sidebar

[puria]

By now the sidebar is divide in two groups:
Signatures
Organizations

But actually what is under organization is under the digital identity realm.
I suggest to think better separation, for users that arrive for the first time in the dashboard.

Actually the homepage says that is platform for interoperable identity strategy but the very 4 menu items brings you to sign documents with pades/xades/cades/jades

I suggest also to invert the order of them... AND DIFFERENT COLOR and LAYOUT to distinguish them, in the same place.
