New release, shop system, bird ai updates

New in this release:

• Start of the shop system, it is fully functional but requires populating with items proporly. Additionally has a placeholder voiceline and shopkeeper artwork which will be replaced later with my own art.
• Birds now spawn outside the garden in an "appear" state, and will only enter if you fulfill their visit requirements
• Journal system has been implemented but is unfinished

Additionally the file size has increased drastically, this is due to placeholder audio files and images which will be cut down at a later time.
