bootstrap: fix minor issues with profile picture cropping

* Add required [1] "display: block;" style property to img element
* Fix image overflow in modal. As cropper size inherits from img's parent element [2] (including padding according to my research), we need to wrap modal body into another div that has the padding we want.
* Remove ability [3] to click away to dismiss the modal as it often interfered with user interaction when cropping.
