New toolbar icons for popular tools

By popular demand, gui/sitemap now has an icon on the main toolbar at the bottom of the screen. Click this button to quickly find and zoom to (or follow) units, locations (like your guildhalls and hospital), or artifacts. You can search by either native names or translated names for units and artifacts.

If you prefer hotkeys, the Ctrl-g hotkey for gui/sitemap still works as it always has.

Similarly gui/mass-remove now has a toolbar button that shows when you click the vanilla "eraser" toolbar icon. The new button shows up next to the other "remove" icons. gui/mass-remove allows you to area select to remove any combination of constructions, buildings, stockpiles, and zones. For buildings and constructions, you also have the option to only remove those that are fully built, those that are planned but not yet built, or both.

###Experimental branch support

If you are subscribed to the DF experimental branch, be sure to also select the experimental branch in your Steam client for DFHack.

PSAs

As always, remember that, just like the vanilla DF game, DFHack tools can also have bugs. It is a good idea to save often and keep backups of the forts that you care about.

Some DFHack tools that worked in previous (pre-Steam) versions of DF have not been updated yet and are marked with the "unavailable" tag in their docs. If you try to run them, they will show a warning and exit immediately. You can run the command again to override the warning (though of course the tools may not work). We make no guarantees of reliability for the tools that are marked as "unavailable".

The in-game interface for running DFHack commands (gui/launcher) will not show "unavailable" tools by default. You can still run them if you know their names, or you can turn on dev mode by hitting Ctrl-D while in gui/launcher and they will be added to the autocomplete list. Some tools listed as "unavailable" in the docs do not compile yet and are not accessible at all, even when in dev mode.

If you see a tool complaining about the lack of a cursor, know that it's referring to the keyboard cursor (which used to be the only real option in Dwarf Fortress). You can enable the keyboard cursor by entering mining mode or selecting the dump/forbid tool and hitting Alt-K (the DFHack keybinding for toggle-kbd-cursor). We're working on making DFHack tools more mouse-aware and accessible so this step isn't necessary in the future.
