Added fallback for event line labels to use the default window font is the one specified for labels couldn't be loaded

Fit Textures: entering floating point numbers in the texture repeat boxes is now less infuriating. Resolves #404.

Improved associations and event lines. Refactorings to make the whole thing more sensible (hopefully). Options to display labels on event lines (can be configured in Preferences -> Editing).

Image Exporter: fixed a bug where it always applied the floor offset, even when exporting the ceiling textures

Color Picker: fixed a bug that prevented all intensity and interval sliders to show up for flicker lights

OBJ Exporter: replaced default folder selection dialog with something more convenient (and more consistent with the rest of the program)

Fix exception caused by horizontal mouse wheel (resolves #409 reported by ioan-chera, reported by KanaiZo)

OBJ Exporter: checking the "Solid" checkbox now adds to following flags to the actor: INVULNERABLE, NODAMAGE, SHOOTABLE, NOTAUTOAIMED, NEVERTARGET, DONTTHRUST

Add support for Line_SetAutomap{Flags,Style}

OBJ Exporter: improved exporting models for use in GZDoom. It can now export models that can be directly used in GZDoom, and also creates the necessary MODELDEF and ZScript/DECORATE code

Image exporter: added options to use sector brightness for the export, create brightmaps (based on sector brightness), and split the image into 64x64 tiles

Sectors Mode: the sectors things are in are only determined if necessary, which should increase performance when switching into Sectors Mode in very big maps

3D Floor Mode: fixed a crash when duplicating 3D floor geometry and there was not enough space in the control sector area

Fixed a bug introduced by addressing #427 that stopped the script editor to show up in vanilla Hexen. Fixes #429.

Fixed a problem where translucent 3D floors were drawn solid. The cause was a rounding error because of the transition from float to double.

The script editor is now only shown if the current game configuration supports scripts. Resolves #427.

Fixed a crash in the DIALOG/SCRIPTS editor when selecting any other than the first two options in the "look in" combo box in the replace tab. Fixes #425.

Draw Ellipse Mode: fixed a rounding error that could result in wrong shapes under certain conditions

Edit Selection Mode, Flat Align Mode: fixed a bug where snapping occurred to wrong positions on lines when the grid was transformed
