Temporary testnet downtime

Read about it here:

A temporary patch has been released (Github link above), but instructions are not yet available and just saving the patched files over the original ones doesn't seem to work.

We'll hopefully make them available this weekend.

Code fixes are in “master”, so those who use testnet can update their systems.

I updated a Win (standalone) and Lin (Fed Node) box by using standard procedures.

On the standalone instance I had to run “counterpartyd reparse” and then “counterpartyd server”, while on Fed Node it was done automatically.
