Execute the edit callback function in a thread. By executing it in a thread
we don't have to wait for longer validation procedures to finish to
continue updating the UI. This is most notable in the MoveGamePopUp
which is heavy on disk IO.
Because we cannot use special text formatting in a thread, the
indicator messages have been reworked while also becoming extensible.
A dictionary of extended reasons can be specified through the
`IndicatorLineEdit.extend_reasons()` method.
The dictionary has to follow the following format
```
python
{
MyIndicatorReasons.REASON: self.tr("Reason message")
MyIndicatorReasons.OTHER_REASON: self.tr("Other reason message")
}
```
In the above example `MyIndicatorReasons` is a subclass of `IndicatorReasons`
which should be specified as follows
```
python
MyIndicatorReasons(IndicatorReasons):
REASON = auto()
OTHER_REASON = auto()
```
Shared: Require an argument to initialize the each singleton, if it is called uninitialized, raise a RuntimeError
InstallDialog: Use QCheckBox label for the information text and remove the layout
LaunchDialog: Minor code clarity improvements
Console: add a Dialog with the process's environment variables
GameUtils: Inherit the system's environment and not a clean one
ImportGroup: Add the ability to automatically import all games in a folder
RareStyle: Use rgb values, remove hex codes and rgba values
IndicatorLineEdit/PathEdit: Infer object names from class name, don't override layout method
Models: Type fields as Optional (`Union[<something>, None]`)
Paths: Use pathlib for everything
