Show attribute's ID, type etc. in Entity-Component Editor

Would this be a toggleable option? Might be inconvenient if those are always shown, though they are very useful info.

Configuration wouldn't hurt I'd guess. Could be optionally implemented as tooltips.

I think if we are talking about EC editor UI capabilities it will get complex quick if everything is shown by default. What I'd like to see:

• Right click the column header -> get menu that you can select what columns are being shown -> the visible columns should be remembered to config.
• Right clicking the column header or possibly anywhere on the tree widget too -> get menu Sort by... -> with name, id, attribute type (get all boolean attributes in a row, not mixed all around the attribute view, imo this should be the default not alphabetical ordering) etc.
• Right click would also have expand/collapse all options. If the UI is done smart with menus, we don't really need anything other than the tree widget itself, right click menus and undo/redo controls.
• Evaluate if the "show entities" side panel is needed at all. Afaik it can be used to unselect things when you are in the middle of multi entity editing. Or possibly it also shows the history of ents that the editor instance has had? I don't really even know what it does, I have never used it and I suspect this is the case with most people.

Most things here also apply to the scene struct window.

edit: I think tooltips in EC editor would be a bad idea. It would then constantly show a tooltip on top of ~everything and using the widget would get a lot more harder/unpleasant. More data columns might be a better idea.

@jonnenauha's ideas sound good. Don't know how well QtPropertyBrowser can be adjusted to our needs, so it might be convenient also to accomplish #637 while enhancing the EC Editor.

If we can get the QTreeWidget ptr or whatever its using we can modify the headers and install event filter for UI actions. But yeah sure making our own at some point would be ideal.
