This commit fixes the occasional issue of xp drops not being highlighted
while flicking prayer from the prayer menu; that is, before this commit
it was possible to select or deselect a prayer between xp drop widgets
being spawned, causing different highlighting for them. This commit
saves the active prayer at the beginning of each tick and uses that
tick's prayer for all widgets unhidden during that tick.
