Settings: avatar choosing button not user friendly

[syfds]

Describe the bug
In settings dialog there is a button to choose an user image. This button has no label and is not descriptive enough for the end user.

To Reproduce
Steps to reproduce the behavior:

1. Start BattleShip application
2. Click on 'Settings'
3. Scroll down to 'User Image'
4. Button has no label

Expected behavior
Button should be labeled with a description, for example 'Choose...' or 'Open an image...'.

Optional: The second dialog with title 'Image Chooser' is redundant and should be removed.
Optional: Choosen image is scaled and showed between label 'User Image' and the button

Thank you @syfds for taking the time to contribute.

The first bug, which prevented you from seeing the avatar the first time you start the game (and also play the game #16 ), should be fixed in the develop branch that once merged with the main one will give birth to the 1.0 release.

I agree with you, it's not clear what the user should do and the image chooser frame is redundant, this is for sure something to address for the 1.0 milestone.
An important point it's also that all images should be resized to 32px*32px - #11
