This commit makes some tweaks that make it at least possible to use lib-linked actions as Pose Libraries. Specifically: * The apply poses button is no longer greyed out * It is possible to select different poses from the list of poses * All pose library operators which edit the poses stored in the poselib now have improved poll callbacks which perform extra checks for lib-linked actions (which cannot be edited, as all those changes will be lost) Caveats: * Due to the way the UI list template works, it doesn't seem to be possible to make it not grey out the items in the list. (While the double-click to rename thing shouldn't be allowed, items should at least look like they can be clicked on) * The difference between clickable vs not-clickable isn't too great, making it hard to tell that that while the Add/Remove/Sanitise toggles are not usable, the Apply Poses is actually functional. But, this is a more of a UI-toolbox level issue
