changed: now [for] statements with the same function can be nested

sample:
[for my_function]
 [for my_function]
   foo
 [end]
[end]

changed: FunInfo::iter has a value from the last [for] statement now
sample:
[for my_function]
 [other_function]
[end]

void other_function(Info &i)
{
// here i.iter is the number of iteration
// previously was always zero
}

changed: small optimization in [for]
the proper function is being looking for only once at the beginning
previously it was searched in each iteration
