Respect "History is off" setting

[aj-ja]

Given there is conversation that has "History is off" enabled, and I use Hangish to communicate, then parts made by me are stored in gmail. Lines made by other participants (that do not use Hangish) are not stored, that is, it appears that I am talking with myself.

There is no option in gmail to delete this conversation that was meant to be unrecorded.

Thanks for reporting this problem. I'd love to have some free time to update hangish so to use the official protobuf library and the reverse engineered protobuf hangouts documentation. That should also fix this problem.
