/* SPOILER ENHANCER SUITE
combines the function of the toggle spoiler and spoiler hover gadgets
hover over spoilers to reveal them, they'll disappear after the cursor leaves the box
click on spoilers to permanently reveal them, then click on them again to hide them

also adds a custom "Show all spoilers" button (only tested on vector 2022)
allows you to toggle all spoilers with Ctrl + Shift + S
designed only for the vector 2022 skin, this may not work on other skins
