A morris: changing "title"s to "tile"s

The '''Civ4ImprovementInfos''' file defines all of the Civilization's improvements as well as their effects, like providing extra food, production or commerce.

All tags must be opened and closed; the first is the "open", the second the "close" tag. If nothing goes inside a "list tag", then it should just be the opening tag with a "/" before the closing bracket. The following tables contain all available tags, as well as their purpose and accepted values.

|-
! style="background:#efefef;" | Tag Name
! style="background:#efefef;" | Description

|-
!iGoodyRange
|The distance from which this goody hut can be seen by a unit
|-
!iUpgradeTime
|The time in turns that is needed on standard gamespeed until it upgrades to another improvement
|-
!iAirBombDefense

|-
|}

===Boolean===

All of these can either be 1 (on, or true) or 0 (off, or false). Be careful, as you can wind up with a double-negative, which the game will interpret as "True".

===Lists (Multi-line)===

All List tags consist of an opening/closing tag, which is shown here, and then each entry within it is another tag with the same name as the parent tag, minus the "s" (i.e. singular, rather than plural).
