Fixed layout of localization XIBs
Removed the pt_PT localization from Uli's branch, since it was largely untranslated, and used the one from master instead.
Make this build on 10.7. Might break building on earlier OSes.
Satisfy some overly picky compilers.
We have this check box that says "Automatically download and install updates in the future." But we only download them automatically. We still ask permission again before installing them.

With this patch, we make good on the description of that box: updates are automatically installed when the app is quit. No user intervention involved whatsoever if they checked that box.

If the user doesn't quit the app for a day after the update is downloaded, we'll show the dialog we've always used for automatically downloaded updates (Install Now / Install on Quit / Skip This Update).
Fixed a no-autorelease-pool leak.
Adding <sparkle:tags> appcast item element, <sparkle:criticalUpdate /> tag

You would use this like:
<item>
    <title>My great update</title>
    ...
    <sparkle:tags>
        <sparkle:criticalUpdate />
    </sparkle:tags>
</item>

The behavior of this tag presently is: rather than waiting for the user to quit the app (or for some large amount of time to pass), the user will be prompted to install the update (with a stronger message) immediately upon its receipt. This behavior could be improved for the manual update case as well.

We can also use this new mechanism to create special behavior for e.g. paid updates.
Prompts the user to update after a week (rather than a day) if he doesn't quit the app.
Updating Sparkle.strings for the new, more strongly worded strings that are displayed for a 'critical update'

Quick hack to make this build again. Should probably just move to Sparkle mainline, now that they're halfway current.
