New theme options

Most worship-presentations you see nowadays present the lyrics entirely in uppercase. Although I like the look of such design, I don't like the thought of not having the lyrics correctly written in my database, just in case I ever wanted to present it the "normal way". I am working on adding this function to the themes, so you can decide by clicking a new button (just like "bold", or "italic") if the entire text shoud be rendered the normal way or in uppercase letter. This feature would also be accesible for the translation lyrics

Sounds like a good option to me. Feel free to open a PR for that when you manage to get it working and we will have a look at it at some point!
