Update README.md to fix typo

[kdheepak]

This is the current README's example:

julia> @macroexpand @infiltrate cond=true
quote
    if cond = true
        (Infiltrator.start_prompt)(Main, $(Expr(:locals)), "REPL[16]", 1)
    end
end

But I think this is what it should be:

julia> @macroexpand @infiltrate cond==true
quote
    if cond == true
        (Infiltrator.start_prompt)(Main, $(Expr(:locals)), "REPL[17]", 1)
    end
end

This is just a super confusing docstring. The = true part was meant as a default argument, not a comparison (ref).

Might be best to remove that altogether...

[kdheepak]

How about this change instead?

[pfitzseb]

Makes sense to me. Wanna reflect the same change in the docstring as well?

I think it might be better in the docstring to use a condition::Bool to indicate that the macro takes an optional argument. I'm inclined to make the same change in the README as well actually:

@infiltrate
@infiltrate condition::Bool

Thoughts?

Makes sense to me.

I did a rebase on top of the latest README in the master branch, and also fixed some whitespace changes. And I squashed all the commits into one commit for making it easier to read.

Thanks!
