[Request] Option to move skill actions to bottom of sheet

[Spappz]

Currently, 'custom' actions (and reactions + free actions) are displayed below the skill actions added by this module. Since there are many skill actions, most of which are far less used than these 'custom' actions granted by ancestry/class/etc., I think it would be useful to move skill actions below them. This way you don't need to scroll for as long, which perhaps saves me a couple of muscle tugs!

Appreciate the phrase "muscle tugs"
