Adding autocomplete for interactive mode

[Code-Hex]

What I did?

I have created complementary functionality in interactive mode #38
But I have something to do.

• Create test for autocomplete.go
• Simplifying autocomplete.go
• In order not to end with log.Fatal etc, Allow all errors of runtime to be received from runtime.Run

I think @cloudson perform the last task earlier than me.

Hey @Code-Hex , about the task

In order not to end with log.Fatal etc, Allow all errors of runtime to be received from runtime.Run

I fixed the problem here. The unit tests have passed but as this work is about the runtime package, I would like that you and @luizperes help me to test it manually.
Basically, each (syntax, semantical and runtime) error should not break the program on interactive mode.
Can you guys help me? After that I will merge it on develop branch.
