This makes it possible for some plugins to detect the game state more
reliably - for example, prospector would previously fail when
embarking if the viewscreen_choose_start_sitest instance had any
children.
The idea is to make ui handling more modular, dispensing with
huge functions that switch or if/else on lots of variables.
For now, used to split up functions in the sort plugin.
Removed t_virtual.
Made lua use C++ compiler
Removed many silly exception types from Error.h and renamed the rest.
Removed Brush classes from tiletypes plugin.
This is an incompatible change to the plugin ABI.
The Console is not thread-safe unless used indirectly
via color_ostream_proxy, so everything should use their
per-thread stream.
Units can be selected via 'u', 'j', 'v' and 'k'; full-screen
unit details view not supported.
Items can be selected via 't', 'k', 'v'->inventory.
Also, when viewing a container item full-screen, the selected
contained item or unit is returned; never the container itself.
The api is used in rename to allow setting nicknames for
arbitrary units, including animals and enemies.
