Automatically generate recall values

[zuckerruebe]

Add syntax for automatically introducting recall values.

SUGGESTION:

Automatically collect all variables ending in a ^, e.g. TIn^ into a unit of type 150 (the recall value type) when compiling the deck.

@ahobeost : Wouldn't that be nice?

@zuckerruebe Awesome idea! How would we handle the initial value for the recall type?

e.g. Tin^ = 42 @recall(Tin, 42)

Or we don't go down the path of extending ddck synatx ever further, but hope for the spyder integration and push for something like postfix completion in spyder to automatically create recall values/types in the editor. That would have the disadvantage of being less readable/more stuff in the ddck file.
