Support the remaining x/profiles messages

[RiccardoM]

Currently DPM is only able to handle a set of message types inside the transaction list present in the home page as well as inside the confirmation page of a transaction.

Since DApps can require the user to sign any kind of message, the following needs to be implemented as well:

• MsgDeleteProfile
• MsgRequestDTagTransfer
• MsgAcceptDTagTransfer
• MsgRefuseDTagTransfer
• MsgCancelDTagTransfer
• MsgCreateRelationship
• MsgDeleteRelatinship
• MsgBlockUser
• MsgUnblockUser
• MsgLinkApplication
• MsgUnlinkApplication
