Tweaks from Sabe

#1909. User can now keep clicking to their heart's content to sell piles of excess eggs/potions (/food, later). Deselect only occurs once the stack runs out.

Also prettified the alert wording when you fail at egg-hatching.

#1938. Changes "Re-Roll" to "Fortify" and creates a button in Alexander's shop for it to live instead of in the Rewards pane.

#1934. Renames and rearranges the "Reset", "Restore", and "Delete" buttons in Settings for better usability.
