Clear storeagent cache and trigger Mac App Store app updates.

#
# Trigger an update of MAS (and softwareupdate) apps
#
# This seems to be all that's needed to schedule an immediate update of
# MAS apps. This should be run as a normal user. You can run this and
# tail the install log to get an idea of what's happening.
#
# You can also take a look at this user's ~/Library/Caches/com.apple.storagent
# directory to get a report on what apps were available, installable, etc.
# For example, for about two days after the iWork x.2 updates were released, these
# updates were considered "update is too recent" as reported in the
# UpdateOperationAudit.plist file. (After about two days they began auto-installing).
# This may simply be a cooling-off period that Apple is providing special-case
# support for since these are special apps. Not sure there's currently a way to
# force these.
#
# Requirements:
# - Mac must have "Install app updates" configured in App Store preferences
#   - bool "AutoUpdate" in /Library/Preferences/com.apple.storeagent
#   - This pref doesn't seem to take if set at the user level. I instead
#     get the Notification Center prompt that new updates are available
#     and Would I like to install them.
# - Mac must be running 10.9
#
# Assumptions (by me, so far at least):
# - User must be signed into the App Store
# - User must be logged in
#
# What would be nice:
# - Some way to easily determine that an update run completed, possibly
#   by reading a cache plist to compare times.
# - A way to force "too recent" updates.
#
# Other relevant bits that don't seem to need to be touched:
# /System/Library/LaunchAgents/com.apple.storeagent.plist
# ~/Library/Caches/com.apple.storeagent
# ~/Library/Caches/storeagent


# clear some datestamps, probably not all of these are needed
