/// <summary>
/// Enhance a string by replacing place holders with values.
/// This should be done after translations, else the translation term is not recognized anymore.
/// To enshure the correct order use 'TranslateAndReplace(string txt)' instead of this method.
///
/// Actual keywords are:
/// item
/// - can be followed by format
/// - should not be followed by preview (not supported yet, gives wrong results)
/// value
/// - can be followed by preview, format
/// dictionary
/// - replaces dictionary entry with string, format is not supported
/// change
/// - similar to preview but shows the change of the value
/// - value should be declared first
/// - can have the parameters:
/// * up,down,left,right,add0,add1
/// - can differ from value preview because an other method for determing randomness for the value is used
/// result
/// - similar to change but shows the possible result of the value
/// - value should be declared first
/// - can have the parameters:
/// * up,down,left,right,add0,add1
/// - can differ from value preview because an other method for determing randomness for the value is used
/// format
/// - can be used every time and defines the formatter of the string cast e.g. '0.0', '##' etc.
///
///
/// Examples for place holders:
/// {value=army} -> is replaced by the actual value of army (if defined in value definitions), e.g. 75
/// {value=army,format=0.0} -> is replace like before but with formatting, e.g. 75.0
/// {value=army,preview=up} -> is replaced by the preview for army when swiping up
/// {item=sword} -> is replaced by the number of swords in the inventory
/// {dictionary=name} -> is replaced by the value for the key 'name'.
/// </summary>
/// <param name="input">Input string with place holder(s).</param>
/// <returns>String with replaced parts.</returns>
