Change if else statement

[amanzholov8]

brief description of changes

1. Changed return statement (issue Change return in main.py #44 )
2. Also changed if-else statement in line 254 to one line expression
3. Updated "Updating fork" section in the README.md file. Changed git remote add upstream git://github.com/Abdur-rahmaanJ/honeybot.git to git remote add upstream https://github.com/pyhoneybot/honeybot.git and also some minor grammar fix

Very nice the fork instruction. The one liner is better in several line as it was as the irc protocol is fairly uncommon.
