- be more strict and humble when allocating memory from the stack
-- in textfield_width(), handle too large lines somehow
-
-- use select() polling where possible for server-client communication
-
-- may err_line store the processed line internally as it does the line count
+- maps are always as wide as high, so only use one of the two values
SERVER:
-- implement field of view / line of sight and obstacles for those on the map
-
- is it actually useful to define map object action ids in the config file?
-- make shape of map (and diagonal movement penalty) configurable in config file
-
- for game continuation, replace re-playing of whole record files with loading
game state snapshots / save files
-- why does an MapObjAct id of 0 fail?
-
CLIENT:
- enable toggling of window borders
- make log scrollable
-- implement server-config-file-like parsing for client-config-files, too
+- repair single window interface config files (fix double use of keycode 100)
