Daily rewards now follow your vote

Something new about daily rewards and economy in general:

+ Before, when you were using the ,daily command, what was stored to know when you will be able to claim again your daily reward was the time you claimed the reward, now it's the time you voted for the bot. So it looks like nothing important, but it is, basically, if you vote for the bot, you can claim your reward later in the next 12 hours of your vote because the cooldown will be the next time you can vote, instead of the date when you're using the command.

+ Back-end changes, I am now using my own API to get votes from Discord Bot List and store them. That mean I can control and do things like I really want, and also that the daily and payday commands will be more faster than before.

+ Related to this, if the API going down, you will simply not be able to use the daily command, but all other economy commands will still be usable of course.

- Equally important, the code is now really better/optimized instead of before, I cleaned up ~300 lines of useless code, so all the weird "issues" of before like a weird latency when using daily command or payday, and all the rest, are a thing of the past now.

So to summarize, it is more back-end changes, I am now using my own api to get and store the votes, etc ... but it's also changing some things for users, like the first thing I said about cooldowns, which was something really annoying.
