Ctrl= and = shortcuts for zooming in.
ChooseBuildingTileDialog gained scale combobox and saves/restores the scale.

Also, the geometry/scale is remembered even when the Cancel button is clicked.
Tile and furniture views no longer call reset() when changing scale.

Calling reset() clears the selection and current index without generating
the appropriate signals.
Improvements to BuildingEd's Furniture dock.

Added a scale combobox.

Synch scale of the furniture view with BuildingPreferences.

Update the list of furniture groups and the furniture view when furniture is
edited via the Tiles dialog.
MixedTilesetModel::setShowLabels doesn't call reset() anymore.

Calling reset() clears the selection and current index without generating
the appropriate signals.
Update MapInfo when a map is reloaded.

I noticed after resizing a building and saving it, a lot object's bounds
were out-of-date while dragging it, and dragging that building from the
Maps dock used the out-of-date map size.
Fixed display issues after resizing a building.

the setNeedsSynch() call is taken care of by BuildingIsoScene::layersUpdated().

Calling MapManager::mapParametersChanged() didn't seem to fix anything but
needs to be done.
Removed unused code.
Tile and furniture views update themselves when tilesets are added/removed/changed.

This pushes responsibility for updating the various views from the user
of the views to the views themselves.

The new BuildingTileEntryView is a higher-level view for displaying BuildingTileEntrys.
Fixed crash with BuildingEd's select+move object tool.
Wall objects are resizable at both ends.
Always use "none" tile in the Rooms dialog for unassigned tiles.

A new Room has "0" for the grime tiles; perhaps they should be set to
noneTileEntry()?
Fixed TileDefDialog allowing duplicate tilesets to be added.
qDebug() -> noise() in tiledefdialog.cpp.
Launch WorldEd from the Tools menu.
