Update V0.4.2 - Minor UI changes

This update includes some minor UI changes and additions.

I've been very busy with IRL stuff and did more work on Eden's Unreal Reach so content is kinda slow rn.

Changelist

• Added new splash screen
• Added play button to pause menu so you won't have to go back to the main menu to choose another room
• Improved the style of the main menu buttons
• Improved the style of the music player
• Improved the entrance to the palace in the garden 
• Changed fog settings in the garden (day and night)
