Hotfix: Compiling on windows failing due to mismatched variable names in the windows curses header.
Fix retarded assignment to non-existent variables from last commit.
Cleaned up redundant #defines.
Hackish fix for undefined viewport size when it's not in options.txt
Removed _maxx/_maxy from catacurse.h WINDOW, as generic curses functions to access them are already defined.
Fixed areas that relied on this.
Fixed the window size options to more accurately represent the actual numbers.
Fixed a typo in the tutorial text.
