Added Update Function to Update the Expanded View for search

Following Functions have been added:

    1. GenerateContentSlice :
	This Function Generates a slice of interfaces which are mostly
	string slices or strings. The Reason for this is the random
	nature of the maps. and also this makes adding songs to playlist
	a breeze as we only need the row number to add the
	song/album/artist to the playlist.
    2. UpdateSearchView :
	this is the Update function for the search view which just
	iterates over the interface slice and draws their content to the
	expanded view
    3. AddAlbum :
	As the Name Suggests adds all the contents of the Album to the
	Playlist
    4. AddTitle :
	As the Name Suggests adds the track to the Playlist
    5. QueryArtistTreeForAlbums :
	This Functions finds all the albums named album in the Artist
	tree and returns an album map. This is because two artists can
	have same album names too.
	Album Map is basically a [2]string{artist, album} -> path to all the songs in the album

Following Functions Have been changed:

    1. AddArtist :
	It now sends notifications.

Following Functions Have been removed:

    1. GetAlbumTree
    2. PrintAlbumTree

    Album Trees are no longer needed
