Update skykey format

MERGE REQUEST

MR Guidelines

Overview

• Split up skykeymanager and skykey code into 2 files
• Update internal skykey format to use 1 type byte followed by 56 entropy bytes
• String representation now uses a URI formatting: skykey:ARPZHZg_eZNlMuCe42N6ntad3gxV1W27XZxPSlw_kts9n_CzF4E4PN5AmOOr_PKybe2udkNUPOnP?name=example

Note that the keys are not yet re-written on disk in the new format. Newly added keys, however, are written using the new format.

Example for Visual Changes

I tested the update from v1.4.8 to this branch by adding statements that print the entire entropy slice. The key name and entropy doesn't change.
