Command to init on a project

[danimesq]

Only CLI, for now

• adds the full web3updater lib installable globally
• its custom new_patch_at.json, updates.sh, update.json, etc
• web3updater init installs it in a specific project, while the global command manages it (app can run a local or global W3U to programatically use it)
• init update.json

cat > /usr/lib/web3updater/update.json <<EOF
{
"patch_at": 0,
"cid_at": "",
"recently_checked_at": "",
"recently_updated_at": "",
"ens": ""
}
EOF
