Update IDEView.jsx

`<Overlay...` has a default `title` of `'Modal'`
https://github.com/processing/p5.js-web-editor/blob/master/client/modules/App/components/Overlay.jsx#L102

many modals are missing a title, so i added some. i made them basically the same as the `ariaLabel` (but capitalized, changed `-` to ` `, etc)
