Trying to preview different saved was more difficult than it
needed to be since after importing a layout, the user needed to
swap to another layout and then back to the original one in order
to see the changes. I changed this so that if a user imports a
layout to the currently active HUD slot, the plugin automatically
swaps to another HUD slot and back.
As a part of this also refined the general slot UI so that the
active slot is indicated in the slot selection UI for saving a
layout to game data.
Also add /phud for swapping between saved layouts.
Currently only the map and chat box have saved positions, although the
implementation supports additional windows. There is a checkbox when
importing to turn on or off window position saving.
Add a system to save layout slots and restore them, effectively
increasing the number of slots to an infinite amount.
Also add crafting and gathering layout swaps and make the UI more
reasonable.
Refactor out the combo boxes.
