1.0 - audio, progress tracking

Having reached all the milestones for the 1.0 release snuck up on me today. Here's the last of the items to make this a full game

• Music because every game needs some background music
• SFX for feeding bitches
• Credits page to credit creators of the above two things
• Progress window to show how many variations of a bitch have been seen
• Bitch Slot buy buttons enable/disable depending upon lust points

Obviously improvements left to be made - primarily more content and better quality content. I'm going to approach MagicalMysticalVA and see if I can get her to record a bunch of custom audio, while I start work on the 2.0 milestones.

Roadmap for 2.0

• New bitch: College Bimbo
• Feature: Gallery of seen bitches
• Feature: Notifications to show when your new bitch is a variant you haven't seen before (increasing progress)
• Feature: Volume sliders for Music & SFX (rather than just on/off)
• Bugfix: Most windows prevent a fast exit (alt-f4) because they're treated as notifications
