//  * This is a bullet point
//  ** {{quote|this is a quote}}
//  ** This is a bullet point after a quote <-- this will have double bullet points

/* 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
also fixes hyperlinks in spoilers visible by default in the cosmos skin
