Fixes

Off by One error, when selecting jump destination through Level
Selector
Trying to load enemy data, when enemy address is 0x0
Stock "Lost Levels" couldn't be played with instaplay
Level Selector wasnt sized properly to show the full height of the
World Map (Windows)
Two identical objects on top of each other would always be selected
together, when clicked on, making them "stuck together"
Graphic data would not be reloaded when a new ROM was opened, leading
to problems when custom graphics are used
Dragging an object from the Object Toolbar would not select it as the
current placable object
Object Toolbar resizing after dragging an object sometimes
Being able to place an object with middle click, while dragging
others/selecting others
ROM didn't save properly, when jump destination had 0x0 as either address
Recent Objects Toolbar not being scrollable, but extending the Main
Window when full
Closing a level would not ask if you wanteed to save
3 items were accessible in the Object Toolbar and Dropdown, that were
not drawn in the Level View. They change properties, that can be
changed using the Editor UI

Adds tab for parsed Found Levels in Level Selector (thx @withthelove)
Makes folder paths more robust under the hood (thx @TomaSajt)
Adds Game Property Editor from Workshop, letting users change certain
ROM values, without patches and adds new values for Big Bertha
Adds toolbar button for Level Selector
Skip most of the curtian animation and all of the start screen, when
using instaplay, starting right in the Overworld
Adds right click option to "grab" an object in a level, to be able to
place it with middle-click; like a Pipette
Level Viewer shows Levels and gaps as Blocks
Level Viewer shows Enemy Address as well now
Level Viewer shows Level Preview in Thumbnails
Adds indicator for vertical flight path of Red Paratroopas
Adds Editor Option to show/hide outlines of Level Pointers in Level
Selector
Toggle additional Starman for instaplay Powerup in Editor Settings
Switch from changing addresses to offset in Level Header, which now
preserves the offset, when changing Object Sets
Adds Test Level entry in Level Menu, to make the feature more discoverable
Shortcut Ctrl+S to save the ROM (How was that not a thing already?)

World Object Palette would not update/save, when changing it in the
World Info Dialog
Map Objects being able to be moved out of the map area (onto the black border)
New Level Pointers spawning outside the world map
Level Menu not keeping track of the current world number, if you
change the order in the World Info dialogue

If ROM was parsed and has saved Level Data, mark it as dirty, if
Scribe moved the Levels around. This causes Foundry to reparse the ROM
making sure no Levels are lost
