apple-gcc42 is now in homebrew/dupes
Update rvm install command

1. Prefer homebrew (otherwise macports gets used if installed)
2. It seems that the command has been updated to `\curl -sSL` instead of `curl -L` for clearly specific reasons.
Switch Admin Settings Lists to Select2.js

 - support for autocompletion
add site_setting choices

 - add site_setting choices lists to list entries
 - allows for handy autocompletion using the new select2.js UI
 - automatically merges plugin choices into existing list, allowing for easy extension
Support for insecure POP3 (without SSL)

Ideally it would be a menu selection to select POP3, POP3S, and potentially other future protocols like IMAP if desired, but I didn't want to deal with data migration at this point.  And then I was going to have a checkbox for "Secure" (on by default, obviously), but that was very hard to word as to how it was different given everything else referred to pop3s and I couldn't change that either.  So I settled on a preference:

pop3s_polling_insecure: "Poll using plain text POP3 without SSL"

Off by default.

This makes it very clear that as to what turning on that checkbox will be, and by calling it "insecure" makes sure people will think twice before turning it on.

I have not attempted to do any of the translations of the preference, I'm ot sure how you handle that.
