Functions for document info and EvPage,other changes
Summary: I added functions in the backend to get document info. Added a member to evdocument to deal with web documents(ePub) on the frontend. Added a webview to the window, that shall replace the Atril view. Due to removing the view from the main Atril window, I have given rise to various GTK-critical errors in response to signals, will be sure to suppress these in the next commit. Worked towards overall blending in of ePub documents.
