Code tour: 10/6 to 10/12

[foxfirefey]

Here is this week's code tour! We closed a total of 21 bugs. Thank you to our submitters this week (in no particular order): yvi, kareila, ninetydegrees, zvi, wyntarvox, piranha, twtd, cesy, branchandroot, sforzinda, yati, denise, gchick, and afuna. Most of these patches aren't live yet; you can keep track of which patches are live on the code status page.
