* Add a background image property in theme
* Add the browse command to theme settings page
The goal was to create a command that permit to browse user pictures.
The user can now select is picture by browsing file or to simply copy the
link of the image in the textbox.
* Try to show the image that we download
* Change the save image method in file service
We call the method `ImportImageFile` so that we can show a picker dialog
and directly import the image in the roaming folder.
We make some check to avoid the application crash, still need to test
* Reorganize the UI for image import
* Add background brush converter
Now that we have a background image we need to set the background according
to the theme color or the selected image.
To do this we need to use the `ThemeViewModel` and the new converter to
select the right brush to use (`ImageBrush` or ` AcrylicBrush`)

* Disable if it's a preinstalled theme
* Add new event when background image changed
* Make the RemoveImportedImage method async
* Subscribe to background image event and change background in code behind
* Add the delete background image command
* Remove unused converters that we created

* Add background opacity property to terminal view model
* Need to create a theme changed event
If we don't notify the view that the selected theme has changed with
another theme that has the same background but a different background image
we'll never see this image appear.
In fact the background change is triggered by the background color change.
* Remove the background from the theme settings page
* Fix error of last edited image
* Fix image background aspect ratio
