First draft of cross-module type checking
...
Currently, all top-level types are imported. No alias resolution
happens so you need to use "import open M" atm.

Create MetadataModule for more refined information about modules

Used in most places to break a module into more orthogonal components.
Some of this data needs to be serialized into the interface files.

Switch the internal data constructor name for tuples. Before tuple
...
constructors could be shadowed by user defined ADT's such as "Tuple0",
"Tuple2", etc. Now it uses "_Tuple0" to make it impossible to overlap
with user defined ASTs.

Convert more files to the new Expression format that relies more on
...
patterns. Seems to clean things up so far.
Also, begin adding a module that resorts definitions to make sure
that each definition comes after the ones it depends on. This will
also make it possible to disallow recursive values statically.
