Doesn't work with "strictNullChecks"

Hey.

TypeScript version: 1.9.0-dev.20160613-1.0.

If I set strictNullChecks in the tsconfig.json to a boolean value, and not using any configuration in the plugin - typeScript({}) - it throws this: Unknown compiler option strictNullChecks.

If I add some configuration to this, and set target to es5 and module to es6 plus set declaration to false within the plugin itself, and set it to use the TC 2 dev. Everything works.

The performance seems to getting worse also comparing to native TSC when you set the TS inline as an plugin option. 4 - 5 ms vs 2 - 3 ms native.

For me it seems that this plugin doesn't work with latest TS 2.0 Pre version? And I think this is the source for the issue? https://github.com/rollup/rollup-plugin-typescript/blob/master/package.json#L34

This plugin also uses itself as a dev dependency with a much older version of the plugin, and older version of Rollup.

Any solution on this issues?
