The main functional change is that PUC will now use shorter HTTP request timeouts when not running inside a Cron task. This is to comply with the WP VIP coding standard that strongly recommends a maximum timeout of 3 seconds.
Prompted by #107
Technically, this is not necessary because that part of the library hasn't really changed, but let's use the same version number everywhere for consistency.
Cause: Debug Bar 0.9 now includes an admin bar menu that lists the available panels. This means that the special element that PUC uses to identify its panel titles (<span id="puc-debug-menu-link-$uid">) is no longer unique. This breaks the JS that's supposed to work around the fact that Debug Bar incorrectly assumes that every panel will have a unique PHP class name.
When multiple instances of the update checker are active at the same time, each will have its own PluginUpdateCheckerPanel instance and its own entry in the Debug Bar. However, since all instances have the same class name, and Debug Bar uses this name to generate link and wrapper IDs, we will end up with duplicate IDs and a semi-broken debug bar.
I've added a bit of JS that will find update checker panels and replace the relevant IDs with new ones based on the plugin slug, not class.
