Border Pawtrol v0.5.2

Border Pawtrol v0.5.2 release

• Swapped the chicken and bunny worlds to have a more even difficulty curve and to hopefully encourage the player to use the bark ability.
• Removed one level from each world so the player sees something new more often.
• Fixed a bug in the chicken bonus stage which prevented the Bark Power UI element from showing up in non-fullscreen mode.
