Hitori 1.3 update

Hello!

In Hitori 1.3 update:

• Fixed a bug that caused a crash in level 1000
• Added level restart confirmation popup window.
• Added max width to layouts for wide aspect ratios
• More consistent back buttons - added back buttons to all screens except Game and Main Menu
• Dropped Android x86 build bcoz Unity can't build x86_64 and it doesn't comply with new Play Store rules for 2020
• Text changes: updated fonts in a couple of places, changed font sizes and margins, fixed line breaking in level 1000, adjusted header sizes and margins, more readable credits screen
• Popup rework, all popups have (x) button and block game input to avoid accidental clicks behind popups
• Blocking move undoing when Check animation is played or when popups are active
• Changed back button behaviour in Game, instead of undoing a move, closes popups or goes to menu
• Prepared parts of the project for future update
• Added more consistency between layouts
