UDBScript: fixed a problem where floating point default script option values would be converted to the system's locale on hot reloading. Fixes #858

Nodes Viewer Mode: fixed a problem where trying to engage the mode with an empty map could crash. Fixes #857

Map Analysis Mode: fixed a problem where lines with fractional vertex positions could erroneously be reported as overlapping

Thing Edit Form (UDMF): fixed a problem where setting floating point values for health wasn't possible. Fixes #225

Stair Sector Builder Mode: fixed an issue where the number of sectors and the sector depth was not loaded correctly when a default prefab was set. Fixes #847

Nodes Viewer Mode: a crash that could happen when the nodes header was interpreted as an UTF-8 value should be fixed for good now (#827)

Improved performance in classic modes when panning the view. This is achieved by parallelizing plotting linedefs and vertices on multiple logical CPU cores. Enabled for linedefs by default. Disabled for vertices by default, since it can cause flickering when vertices are close to each other. Settings can be changed in Preferences -> Appearance

UDBScript: setting an UDMF string field to an empty string will not remove the field anymore, but actually set it to an empty string

Reverted change that added lighting effects to the generalized sector effects. The lighting effects can actually be set through the regular effects, so it's not needed in the generalized effects tab

Disabled visual sloping for game configurations that do not support plane equation slopes. Fixes #828
Added toasts for visual sloping events

Improved UDBScript to version 5:

- Added Plane class
- Added BlockMap, BlockEntry, and BlackMapQueryResult classes
- Sector class
  - Added getLabelPositions method to get the position of sector labels (where tags, effects etc. are displayed)
- Added support for JavaScript BigInt for UDMF fields. This means it's not necessary anymore to use UniValue to assign integers to new UDMF fields. Instead it can be done like this: sector.fields.my_int_field = 1n;
- Added type information file (udbscript.d.ts)

Behavior can be configured in the "Toasts" tab in the preferences.

3D Floor Mode: added support for UDMF game configurations without support for sectors with multiple tags (i.e. Zandronum)

Game Configuration dialog: fixed an crash related to required resource checks when switching through the game configurations too quickly. Fixes #813

Resource options form: fixed a problem where the text box containing the path to the file could be focused. Fixes #806

Fixed a potential crash when adding DECORATE files to game configurations that check for required resources. Fixes #808

Things Mode: fixed an issue where the thing info panel did not show enum values for the first argument. Fixes #804

Tag Range plugin: fixed a problem where the new tags were not displayed in Sectors Mode when selection numbering was disabled. Fixes #795

Boom game configuration: added missing lighting effects to the generalized sector specials. Fixes #799

Sectors Mode: fixed a regression where sector labels were not updated after editing sectors. Fixes #793

Fixed a regression where editing map elements did not preserve the selection order, but used the index order instead. Fixes #791

Fixed regression in resource list editor where it'd get fucked if the user has non-standard UI scaling enabled
