NetherGen: Now generates SoulSand.
Fixed generator adding values to ini file.
Merge branch 'master' into IniFileFix
IniFile: Split SetValue() into AddValue() and SetValue().

Each function does what one would assume - AddValue adds a new value, SetValue overwrites existing value (creates a new one if not exists, if instructed to do so).
Documented the cIniFile:AddValue* functions.

Now the documentation really matches the implementation.
