Several bugfixes and improvements

The following things are done:

• Forwarding URLs with text (e.g. "Check this out! ") will not give errors anymore.
• Removed some words that could break the search (ft. feat. meets.) and weren't used with the new search method before.
• Removed the first check and reply by the bot, this speeds it up quite a bit.
• The bot has a new name "Shifty".
• Still looking for a new icon/avatar
• Cleaned up code.
• Add requests and Ujson to speed up the bot (a lot).

First release

This bot gives back a Spotify-URL if you send it a Youtube-URL

A few things to note:

• Youtube titles without a hyphen (-) will give no results. A Youtube video title MUST in every case have a hyphen between the Artist and the Title of a video.
• If a track is simply missing on Spotify the bot will reply with a message that it couldn't find that song.
• Any kind of Youtube-URL will work (youtube.com?watch=v, youtu.be/v, youtu.be/, youtube.com/embed/, etc)
• If a Youtube title includes parentheses containing the words 'remix' or 'edit' it will search for that particular remix or edit. If there's something else between parentheses the parentheses including that text will be removed to widen search.
