Ok, the blockchain explorer is now fully synchronized!

• The nonstandard transaction was an isolated case (search for "nonstandard" in the explorer to see it or check if other appear in the future)
• The multisig address that was mentioned previously is now present, it was in the blocks after the nonstandard one.
• I've added the two active pools I could find (YPool & UpCPU), though extraction stats are not very interesting right now as YPool just dominates with 95%.

Feel free to test and check things to see if everything else is okay!
