pundle-typescript doesn't report type errors

[appsforartists]

According to https://github.com/Microsoft/TypeScript/issues/4864, the simple transpileModule function in the TypeScript compiler only reports syntax errors (which is what babylon gives you anyway). For real errors, we'd need something more sophisticated, likely using language services to watch the filesystem. pundle is already using chokidar for watching.

TBD:

• Is there a way to replace pundle's watcher with TypeScript's when using pundle-typescript?
• What's the performance impact on letting both do the watching (pundle for bundling and TypeScript for error reporting)?
• How much work it would be to write a Language Services-based pundle plugin?

That's actually a very good idea for the v2 struct. Thank You

Note to self This has now been fixed in the v2 struct by allowing all components to specify a activate() and dispose(). In theory a pundle-loader-typescript should be able to setup it's watchers on activate(), report any errors it sees on this.report(error) and when all compilation/watching is done, it can just dispose the watcher on disposes()
