overhaul of Instagram-Bot

I used your original version as a base for a script I wrote for a contract. I decided to refactor the code and here is what I got in the end.

I also added a 'maxlike' in which the script will sleep to avoid instagram rate limiting.

I have no real idea what those regexs are really doing, so they are here to stay it seems, other than that, I think it is definitely more readable.

Cheers,
