Don't enforce naming restrictions in ambient declarations

[RyanCavanaugh]

There are some modules like this:

export declare namespace Foo {
  export var static: any;
}

We flag this as an error:

../../throwaway/clipboard.ts(2,14): error TS1214: Identifier expected. 'static' is a reserved word in strict mode. Modules are automatically in strict mode.

This is a mistake -- it's possible the actual library says something like e.g. Foo["static"] = expr, rather than actually making a literal static local; we should not treat this as an error. This is blocking some actual .d.ts files on DT.

is this blocking the definitelytyped work?

[RyanCavanaugh]

Yep. We can't convert some things to proper UMD because the definitions end up in a module.
