Profile editing with vault #249
Description
Currently the Vault doesn't allow profile editing.
We should implement it, and delegated sites should redirect to Vault when users click edit profile button on their sites.
Notice that currently Vault doesn't talk to any HM gateway/daemon server. All the data is stored encrypted in the vault, including profile and capability blobs.
We may need to reconsider this, and store public data on an HM-compatible storage server, such that it's easier to propagate it across the network.
Also note that Vault has information about all the delegation sites and server. So things like editing profiles should be possible to get propagated to all those relevant sites at the time of the update.
