sonarcloud warnings 9 (#1511) 
* refactor: const correctness 

* refactor: fix some implicit conversions

* refactor: make local pointers const if their objects are not modified

* refactor: do not cast away const in torrent-cell-renderer

* refactor: remove call to deprecated gtk_icon_size_lookup_for_settings

* refactor: member functions that do not mutate their objects should be declared const

* chore: do not end comments with a semicolon
