1. race/alignment/attack damage type/attack range show corresponding icons
2. attack damage type/range now use comboboxes for custom dmg types/ranges
3. quit confirmation added to cancel button so that user doesn't accidentally lose their data
* New "Apply" button in preferences dialog that is used to quickly apply the GUI2 theme, no restart needed.
* gui initialization reorganized a bit. gui2::init() now responsible for reading themes from file only. Actual theme switching and activation done by gui2::switch_theme(). preferences dependency removed from gui and moved to caller of gui2::init(). gui2 tests updated accordingly.
Map/Scenario Editor
* Rename Load Map to Load Map/Scenario (since it can load both), Edit Scenario to Edit Scenario Settings, Save Map to just Save.
* Rearrange menu order
* Add icon for the preferences menu item (used the preexisting settings.png icon)
* Open folder correctly at Add-on's scenario directory instead of editor/scenarios. (#8910)

* Show warning when maps are saved in scenarios folder or vice versa (#8911)
* Unit List moved to Units menu from File menu to reduce some pressure from the latter.
* Status Table menu item disabled since it does nothing. (Should be reenabled once the functionality has been added.)
* Improve reload functionality in Editor (F5). Reload happens directly from memory and no temp files are needed. Also, the undo/redo stacks will be preserved. (#9024)
Time Schedule Editor
* Browse buttons now set wesnoth style paths instead of just pasting the absolute path returned by the file dialog
* Change text boxes from inactive to uneditable.

Add-on menu
* Two new menu entries for (1) opening the Add-on selection dialog, (2) opening the folder corresponding to the Add-on
The open add-on folder option shows a GUI2 file dialog at the add-on's folder which can be used to open any file. If it is a loadable map/scenario it will be opened in the editor, otherwise the OS's default application for that file will be opened.
File Dialog
* Redesigned with new icons
* New Open External button that opens selected file/folder in the platform's default application (independently of what pressing Open would do). This could be used to quickly open a folder or preview the file before actually selecting it.
* Extension checking and filename validation. (See #8911)
A rich text label widget that can show text marked up with help markup.
Also includes the GUI Test Window, accessible in the title screen after launching wesnoth using --clock option. It can be used as dialog template/example or as a place to test GUI2 code.
The link with details about individual compaigns is useful to players,
even if they aren't looking to become translators. So move it upwards.
The text about first-time players seemed confusing to me, as the choice
is already limited to languages that the player can read. Reworded it,
but after discussion in the PR, neither version was better than just
removing it.
* Redesigned the version dialog to serve as a general purpose About dialog.
* Credits button removed from title screen
* Moved community dialog contents to about dialog as new tab
