Documentation: Improved Amethyst markup in command/variable docs

Whitespace only acts as a separator in Amethyst; replaced the
now-meaningless newline escape chars with a custom macro
(cbr = console break).
Documentation: Script for generating wiki pages for commands/variables

Expected to be run in "doomsday/doc".
Merge branch 'master' of ssh://github.com/skyjake/Doomsday-Engine
Fixed: Passing a de::String to Con_Message() instead of char*
Documentation|TextMate|Mac OS X: Added a .tm_properties for the Amethyst docs
Fixed|Window Manager: Incorrectly changing away from maximized window

The 'maximized' flag is now cleared when changing the window's
attributes (x, y, width, height). This fixes a problem where the
window would stay in the maximized size when changing the window's
resolution while the window was maximized.
Documentation|Console: Fixed typos and some redundancy
Documentation|wikidocs: Improved index table formatting
