gui_chili_docking.lua: fix https://code.google.com/p/zero-k/issues/detail?id=882 (minimize button broken if widget is removed).
and... save window position even if docking not enabled (useful for custom exotic arrangement).

to make the fix work, additional information added to the following widgets:
gui_attrition_counter.lua
gui_chili_chat2_1.lua
gui_chili_crudeplayerlist.lua
gui_chili_ctf.lua
gui_chili_docking.lua
gui_chili_minimap.lua
