On large insert (e.g. paste), client-side method execution failed

[rocketraman]

Paste a large block of text into the editor. An error similar to the following will occur in Swarm.js and the insertion fails:

method execution failed Spec {value: "/Text#10!2y4wk+A0017r~0.insert", index: 23} Object {2y4wj+A0017r~0: Object} Error: malformed timestamp value: 2y4wk1T0

Having taken a quick look I believe this problem is happening because when a lot of inserts are done in a very short span of time (as in a large paste), the RichText.js CRDT appends a sequence number to the operation timestamp for uniqueness. When enough of these sequence numbers are used, the timestamp becomes longer than expected by the parser in Swarm.js SecondPreciseClock.parseTimestamp.
