Proposal: Change to library proposal process

[Yitzchak Gale]

I am in favor of Ian's proposal, with the following additions:

o A proposal must be accompanied by a concrete patch, or
code, as appropriate. The patch or code should preferably
not be included in the proposal message; it should be posted
somewhere on the Internet, with a link to it in the proposal
message.

o One option is that a patch be attached to a Trac ticket;
however, in that case, the proposer takes responsibility to
close the Trac ticket immediately at the end of the discussion
period if no consensus has been reached.

o If consensus is reached, there is then required to be a Trac
ticket with a patch attached, if it does not already exist.
A link to the discussion thread must be exist in the ticket.

Thanks,
Yitz
