Base code for Stream Tip support.
Fixed an error caused when rolling a giveaway through the chat.
Keyword giveaway is back, use !giveaway or !raffle to join (it's replying instantly about someone joining at the moment, will change soon), some features are missing including opening/closing entries, these features will be added soon.
Channels using the bot now report to a server (big thanks to Illarvan!), that's for me to keep track of how many users I get and soon you'll be able to see a list of other channels using the bot in the About page of the bot.
Some fixes to the donations list.
