add a search function

[Aturok87]

adding a search function to allow it to search for a song across youtube like this

::play shepard of fire

{gives list of top five songs matching title here} then allows for number input and adds it to the queue

Definitely - add that and the bot is perfect in terms of ease of setting up and use.
