feat: support implicit evaluation #46

Evaluate statements and print expressions without using the 'e' or 'p' commands.
To avoid cognitive stress, one-letter variables require the 'p' command to view.
But assigning to one-letter variables does not require the 'e' command. :)

Also included:

• default to "h" for empty commands when no previous command exists
• avoid overwriting previous command for specific commands not worth repeating
• avoid overwriting previous command with an invalid command
• avoid overwriting previous command with an implicit evaluation

@slembcke With this change, is the explicit e command even necessary? :)

Edit: nevermind, answered my own question. the explicit eval can be used to overwrite the previous command, which lets you repeat the evaluation by using an empty command immediately afterwards. Implicit evals are not repeatable, so you can do a quick evaluation and continue stepping with maximum efficiency!
