Hi guys,

I've seen some minor annoyances while using the application regarding the notification toastrs.

1. Their position at the bottom-right cover the actual player controls.
2. Sometimes I play around with likes and when I unlike the song, I get a success toastr, this both are green and a bit hard to distinguish.
3. The 'default' css theme for toastr doesn't go well at all with the app.

Edit:

I've made a pull request with fixes for all of the above 3:

1. Moved position to top-right (settings icon is no longer there, so this way the toastr's do not interfere with the application in any way).
2. I've changed the remove song toastr to a warning.
3. I've changed the color scheme using colors from https://flatuicolors.com/, and also removed rounded edges. (the entire interface is based on strong defined corners, the toastr's just didn't belong).
