Enable --type-check option by default again

[sanex3339]

Hi. After 4.0.0 version, i got many problems with --type-check option that disabled by default.
Now in all mocha tests (running with CLI or with WebStorm IDE Interface) i should add TS_NODE_TYPE_CHECK environment variable, because without that all tests are failing due to typescript compile errors.

It is possible to revert back this change or add more global way (through config file) to enable typeCheck option?

You might want to see #412 - you should be able to use the register specified there.

It seems that type-check was disabled so that the default behavior may remain fast.

The things you ask for already exist, you just need to check the README. There's config options listed in https://github.com/TypeStrong/ts-node#configuration-options and there's also ts-node/register/type-check defined in https://github.com/TypeStrong/ts-node#programmatic. Feel free to open a PR if these docs are inadequate.

What does this mean? It's failing because of TypeScript compile errors when there's no type checking?

thank you. ts-node/register/type-check works.
