Fix seed problem

[mykeehu]

There's a problem with using the seed, the green button is missing, which reads the current seed and enters it into the field, and the dice. It would be worthwhile to switch to this instead of the two buttons, because the seed is not displayed on the interface (no info block), and even if I mark the fixed seed, I still can't see it.

Try these steps:

• generate an image with random seed
• click on the fixed seed, generate a new one
• click back on the random seed, generate again
• the seed field content does not change, so if I use fixed seed again, I would use the old one, not the last one.

There's a partial fix for this, the initial random seed is now returned to the box and I added an info textbox to show the last generation parameters.

I will look into the original buttons from the standard UI.

Thank you for quick fix!
