Bug: building default image url improperly

[obnoxiousish]

Setting.cs

 public string DefaultIcon { get; set; } = "images/default.png";

this needs to be /images/default.png i believe, as of right now when it builds a EPG file itll make URLs like "https://master.obnoxious.lolimages/default.png"

note the missing / between l and i

It seems the lead dev on this project doesnt read open issues despite actively maintaining the project so i might make a pull request (but it might get ignored) or idk

Note: Seems the backend may have support for changing this string but the frontend does not, (guessing, the websocket for saving settings sends it over.)

Check with the latest and reopen if need be.
