Object creator can make itemgroups (CleverRaven#58750)

* Basic functionality

* Refactor, styling

* refactoring, item name i tooltip

* Lose a column in the entries box

By setting a background color we can do without the GI column

* Add listwidget_drag

* Add entrieslist and distributioncollection classes

They are used in new commits down the line

* Adjust main menu to accomodate the new item group button.

* You can now drag and drop items into the lsit

But in this commit the json isn't properlty updated so it needs to be added back in later.

* Can now write basic nested json

* Re-did the layout for the entries box

* More layout

* Did most of the layout

* Solved a drag and drop issue, all properties update json now

* Formatting

* Prevent useless json, add tooltips
