BIG Fonts, Token golfing+optimisations + #include for engine lib

New Features

• Added BIG font support for print_line()
• Reduced token usage, thanks to @sparr's token golf + optimizing efforts 🙏
• More code-tidying & token reduction of the core engine
• lmproved scumm8.p8's "template" game - added other char to talk to, items to pickup, etc. for quick testing/reference
• Reinstated Monkey Island "Thimbleweed Island" mini-game (when USE-ing the Computer) in game.p8

Fixes

• Fixed ability to cancel/overwrite UI commands
• Fixed "face opp dir" code and cutscene end
• Added missing luamin exclusions (for "doors")
• Fixed default action logic (e.g. open/close) when needs to "walkto" beforehand
• Fixed "use" positioning

Noteworthy/Breaking Changes

• Now using latest main picotool branch (no longer using scumm-8 fork) - as latest luamin now supports passing of "exclude" list.
  Scumm-8's picotool fork will be archived, as no longer required (+very old!)
• Now uses #include for engine lib in \src files + build merges dist output into new code "tab"
  (but can now also use #include in your own games too - esp. for multi-cart, all share same lib!)

Depth "Auto-Scaling", Skip Dialog & much more!

New Features

• Fake 3D depth "auto-scaling" of Actors (affects size and walk speed to simulate distance)
• Now made "Scale" an Actor/Obj property
• Actor path-finding now more precisely walks to target point
• Added offset X,Y position for talking overlay sprites
• Actors and Objects can now have animations (via do_anim())
• Can now specify default verb for clicking on inventory items (e.g. LOOK-AT)
• Skip current dialog (left-click/Z)
• Skip cutscene (right-click/X)
• Added UI settings properties (for easy custom UI theming)

Fixes

• Fixed "Walking to Object, then clicking diff Verb does latter"
• Fixed "USE" display (and also sample Game "bucket" logic)
• Fixed hover obj display when executing
• Fixed error if specify invalid sprite state
• Fixed issue for actors without walk anims (defaults to "idle" anim)

Noteworthy/Breaking Changes

• Auto-depth actor scaling is now on by default
• New UI settings properties must be set on game start-up
• Refactored do_anim() function's anim_face param is now face_towards
• Token count and character count have increased a lot as a result of the above changes - meaning less space for actual game content. However, you could always try spanning games across multiple carts, like I just did with my game: "CODE-8"
• enable_mouse property removed - now always on by default

Bugfixes and UI updates

• Now all UI colours reflect user-config
• Now possible to disable "diagonal squeeze check" in pathfinding for walking
  (using enable_diag_squeeze = false)
• Made CAM_X a public variable
• Changed say/print_line to have duration overload
• Now skip cutscenes with any mouse click
• Now arrow hover colour to UI setting
• Fixes #11 bug in demo game
