Description

WHAT:

The same pragma key can be used multiple times in a script however only the last value remains. For instance,

#pragma stuff once
#pragma stuff twice

Results in the pragma value for key 'stuff' being 'twice'. It can be desirable to retain all values for a key as a set (preserving creation order).

Incidentally, the getParsedText() script method should output the pragmas since they are quite necessary ro retain script functionality.

HOW:

The value of a pragma will become a set (LinkedHashSet) of objects as soon as more than one occurence of the key (and a different value) are used.

The debugger will get a new flag to output pragmas (false as a default, true when used through getParsedText()).
