Started documenting some details on how I maintain the bug fix branch(es).  Also added some details on how cherry-picking merge commits works, adapted from an e-mail I wrote some months ago.  Still need to describe the steps for preparing a bug fix branch for a release.
Mostly finished the dicussion of maintaining bug fix releases, and modified the release procedure to account for them.  There is a mention of 'updating the changelog' that is left hanging, but I will try to address that in #695.
Merge pull request #940 from iguananaut/issue-940
