floCrypto v2.3.3b

Browse Source 
- Added floCrypto.tmpID: generates a random floID with no private key (use this only for one-time id)
- Added toFloID(address): returns equivalent floID (btc-segwit address NOT supported)
- Fixed bug: legacy addresses of length 33 not working in verifyPubKey and validateAddr
