Clean up some options.
Fixed some compiler issues.
TSify Verifier
Merge branch 'nat' of https://github.com/mozilla/shumway into nat
Completed port of old Verifier.
Finished with the Verifier for now, waiting for all other pieces to lineup before continuing but it works with current infrastructure.
Gowing away from compiler IR generation, using TS now.
Ported most of the IR nodes to TS, AS nodes remain.
Ported over compiler middle end, not tested but it compiles.
Introduced a lighter weight AST serializer.
Next, get compiler up and running and remove old IR.js and backend.js.
Next, port builder.js.
