Maps are now reloaded the same way as tilesets, by swapping the internal data of the MapDocument rather than replacing the entire document. This also means undo history is kept, since the reload is added as an undoable action. This fixes map reload to also affect instances that are open as part of a world. Previously, the old version would stay open in the world. However, maps that are only open as part of a world are not yet watched for changes. This is a somewhat risky change since the code was never prepared for the map and its internal structures to be replaced entirely without any specific change events. New "DocumentAboutToReload" and "DocumentReloaded" events were added, which are hopefully handled in all the right places. Selected layers and objects, as well as expanded group layers, are restored after reload by ID. This change also addresses several issues with reloading tilesets. Added tiled.assetReloaded signal to the scripting API. Most scripts will not have to do anything,, but some might. Fixed enabled state of Reload action, which shouldn't be always enabled for maps (since we can only reload maps when they have a file name and we know the file format). Closes mapeditor#3927
When a map is loaded as part of a world, or a tileset is loaded as part of a map, but not open in its own editor, previously its file was not watched for changes. Now these files are also watched. When a change is detected and no unsaved changes are present, the affected map or tileset will be reloaded. Closes mapeditor#1785
I've extended the changes in this PR with another change that makes sure any loaded document is watched for changes on disk and reloaded when appropriate (when it doesn't have unsaved changes). This not only applies to maps loaded as part of a world, but also to tilesets that are loaded as part of maps (issue #1785). |

This is a re-implementation of the way maps are reloaded, to make sure the reload affects all instances and not just the opened editor tab. Previously, the reload was implemented by closing and reopening that tab, which was only a viable method before the implementation of worlds.
This is a rather risky change since the code was never prepared for the map and its internal structures to be replaced entirely without any specific change events. There's a high probability of leaving a roaming pointer somewhere.
Marked as draft because there are a few open tasks:
Fixes part of issue #3927 (though not entirely, since that would require watching map files for changes also when they aren't open in their own tab).
