Implement History Command and the Shell Expansion Partially.

[Attacktive]

Well, I kind of implemented #10 myself.

Here's what can be further improved:

• the alignment
• !-n and string operations mentioned in the man page
• Record → Array<string> conversion is somewhat hackish.
• the code since I'm fairly new to TypeScript

Great stuff - thank you for contributing! I'll leave this open for now and review it once I have more time.
