identifier Analyzer: should recognize variables of for loops

[treinen]

there is a third case of identifiers that should be recognized: variables that are only assigned
by the iteration of a for loop.

[Niols]

There are also the variables that are assigned by special built-ins. I can think of readonly, local and read, but there might be more of them.

assignement to loop variables does not appear as assignement word in the concrete syntax tree, so this wasn't a good idea. And the detection of for loops is already covered by the structure analyzer. However detection of special buildins concerning variables should go here, as suggested by Nicolas.

the parameter analyser (previously known as dollar analyser) keeps track of the loop variables of for loops, and filters them out when looking for occurences of non-expanded variables.
