Title: Tweaks for OS X 10.8 / force load in launchctl

I'm not sure whether the instructions were previously untested or whether Mountain Lion is the cause, but running launchctl via sudo with the -F flag completes the installation. Here are the commands I tried and their output.

$ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
Could not open job overrides database at: /private/var/db/launchd.db/com.apple.launchd/overrides.plist: 13: Permission denied
launch_msg(): Socket is not connected

$ sudo launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
launchctl: Dubious ownership on file (skipping): /Users/damon/Library/LaunchAgents/homebrew.mxcl.redis.plist
nothing found to load
