Add uniqueNames option.

[fabiandev]

This is an approach to handle duplicate type names via the API, while preserving backward compatibility through the newly introduced option uniqueNames which defaults to false. Fixes #112.

Can you add a test?

[domoritz]

I don't understand the test. It just tests whether string constants work, doesn't it?

[fabiandev]

It tests whether different types of the same name can be obtained with the uniqueNames option. I've just added the string literal to easily see that both types MyObject from main.ts and other.ts can be generated. Since there are other tests that actually test the JSON schemas, this one should verify that the newly introduced option uniqueNames works alongside the getSymbols method.

[domoritz]

Thank you! Shouldn't this option be the default? Could you rebase against the latest master?

[fabiandev]

Yes, probably this option could be default, but I wanted this pull request to be backward compatible. I will revisit this PR and will also resolve the conflicts.

[domoritz]

Thank you @fabiandev

[domoritz]

Could you rebase the branch so that I can merge it?

[domoritz]

Looks great except for one question.

[domoritz]

What does this method do here?

[fabiandev]

Thought it may be more clear to use function overloading here. Could also be removed, since the implementation with the optional parameter should do.

Thank you!
