Text formatting in session description and hyperlink formatting

Would be very handy to have formatting in session descriptions, see no reason not to. Also, I think we need a way to format URLs, with custom text displaying instead of long ass links. Because this isn't a feature, I have to put URLs under spoilers in guides, so it won't visually clutter everything. Another thing that comes to mind is underlining (I mean, we already have strikethrough, might as well)
