Quasiquotations are inadvertently expanded

[jgrosso]

Because the parser expands quasiquotations, and we run Axel source through the parser to convert it, e.g. `(=macro ~name (~args) ~@body) is converted into (AST.SExpression (GHCPrelude.Just (, "src/Axel.axel" (SM.Position 22 55))) (concat [['=macro] [name] [(AST.SExpression (GHCPrelude.Just (, "src/Axel.axel" (SM.Position 22 69))) (concat [[args]]))] (AST.toExpressionList body)])))... which is less than ideal.

Is there a foolproof way to undo quasiquotation? Is it OK if we accidentally "unquasiquote" manually-user-generated code (in the rare case that a user's code happens to replicate the behavior of quasiquote)?
(Maybe a good heuristic is: If the metadata is Nothing or not a literal value (e.g. it references a variable or something), it's user-generated; otherwise, replace it with quasiquote? Can we safely tell the users that any custom metadata literals they provide may be changed without notice?)

We will have a flag (etc.) for the parse methods that will disable quasiquote-expansion, (maybe hygenisization,) etc.
