Dropped the script preprocessor introduced to fix the broken scripts. The parser has evolved in the meantime and can deal with it accordingly.

-	Demented as it may sound, the success of a parsing operation in the
-	original BRA depends on what has been parsed before. The game features
-	an innovative chaos system that involves the parser and the very game
-	engine, in order to inflict the user an unforgettable game experience.
-
-	Ok, now for the serious stuff.
-
-	The PreProcessor implemented here fixes the location scripts before
-	they are fed to the parser. It tries to do so by a preliminary scan
-	of the text file, during which a score is assigned to each statement
-	(more on this later). When the whole file has been analyzed, the
-	statements are sorted according to their score, to create a parsable
-	sequence.
-
-	For parsing, the statements in location scripts can be conveniently
-	divided into 3 groups:
-
-	* location definitions
-	* element definitions
-	* start-up commands
-
-	Since the parsing of element definitions requires location parameters
-	to be set, location definitions should be encountered first in the
-	script. Start-up commands in turn may reference elements, so they can
-	be parsed last. The first goal is to make sure the parser gets these
-	three sets in this order.
-
-	Location definitions must also be presented in a certain sequence,
-	because resource files are not fully self-describing. In short, some
-	critical game data in contained in certain files, that must obviously
-	be read before any other can be analyzed. This is the second goal.
-
-	TODO: some words about actual implementation.
