Added circular thumbnails to the catalogue list view, like the ones in the library list view (#616)

* Added circular thumbnails to the catalogue list view, like the ones in the library list view

* Moved setImage to CatalogueHolder parent class and adapted the code so that when the manga is initialized, the thumbnail is set both in the case of grid and list

* In catalog, when switching between grid and list, initialize mangas only if going to grid view or if over wifi
