TFS XML parsing of attacks and defenses which call lua scripts is not supported

[soul4soul]

Some creatures spells are too complex for the TFS XML spell system. In order to support complex spells TFS XML monsters supports calling spells written in lua. This is accomplished by adding a spell element with the attribute name "script" and a attribute file which is a path to a lua file. OT monster converter skips parsing these spells.

Adding generic support for these spells would be more difficult then the spells which use the XML spell system. What would be feasible is to parse the information and use it when converting to another TFS monster format that could use lua spells. This would means the spells would be parsed and written in a TFS XML to TFS revscriptsys conversion. The spells would be dropped when converting to non TFS formats.
