This is the first attempt to finally implement the require() function
on Lua. The main problem was how to solve conflicts between plugins
that use the same library name. Here we separate each plugin like in a
namespace, so require(name) inside a plugin will save the module in
_LOADED["pluginName/libraryName"] to avoid conflicts with other
libraryName from other plugins.
We can use:
Image:clear()
Image:clear(color)
Image:clear(rectangle)
Image:clear(rectangle, color)
If the color is not specified it will be the transparent color of the
image.

* Now a Cel has a z-index property to change the order of layers per frame
* A new doc::RenderPlan class can calculate the order of cels to be rendered
* z-index is saved as a int16_t in the .aseprite files
* This new field can be set/get from Lua with Cel.zIndex
Now the equivalent was "{tag}_{frame1}.png", but it looks like a
regression reported here https://community.aseprite.org/t/17253 were
it was possible to just specify the frame number as in "{tag}_1.png"
Added a Sprite.tileManagementPlugin property for plugins that want to
replace the standard tilemap/tileset interface. This includes a new
external file field in .aseprite files to specify that the sprite
tiles are controlled by a specific plugin.
Once this property is set, the standard tilemap/tileset modes
selectors will disappear and the only way to make then available will
be setting this property to nil/empty string again.
Fix https://github.com/aseprite/Attachment-System/issues/21
Actually it looks like a long-standing bug in the write/read_tileset()
functions where tileset names aren't saved (so another bug fixed with
this change is that restoring a tileset from a crashes session/file,
will restore the tileset name correctly).
If the current UndoState doesn't modify the "saved state" (e.g. there
is a sequence of undoes/redoes that doesn't modify the saved version
of the sprite compared to the current one), we can indicate that we
are in the saved state anyway (!Doc::isModified).
