Closes #1479.
Allow >> in type generics syntax

We support this in a similar way to the way parsing regexps work.
When we look for the `>` we let the scanner treat `>>` as `>` and
decrease the position of the scanner so that next token it sees
starts after the first `>`.

Split System.register into .register() and .registerModule().

Closes #1500.
Add parsing support for more type syntax

This adds support for

 * ArrayType
 * CallSignature
 * CosntructSignature
 * ConstructorType
 * FunctionType
 * IndexSignature
 * MethodSignature
 * ObjectType
 * PropertySignature
 * TypeParameter

The only remaining type syntax left from TS 1.0 is the TypeQuery type
expression. (Interfaces and declare as well).

This does not yet add runtime asserts for any of these.
Pass options object into scanner

This is tested by making sure that the options used by the
PlaceholderParser are propagated to the scanner.
Fix issue with windows file paths

parser. These are just stripped at this point.
Add option --require to support node require() calls for modules=register

Pass relativeRequire as argument to module instantitor.
ModuleTransformer adds 'require' parameter to module instantitor.

Fix FindVisitor to not start the visiting in the constructor

We used to call visitAny in the constructor, which lead to bad
API where we had to set things on this before calling super.
