This move the finding of links and the creation of a `linkpreviewer` into c++. - The links are now extracted from the text in `texthandler` - The `messageeventmodel` now creates and stores `linkpreviewers` for events that have links in the current room. Two new model roles have been created to let a text delegate know when the link preview should be shown (`showLinkPreview`) and pass the link previewer (`linkPreviewer`). Empty link previewer are returned where link don't exist so the qml doesn't have to have checks for whether the parameters are undefined.
