Rewrite Session backend

    Add session.hpp, containing structs that describe session data

    MainWindow, SubWindow and WebView can be created from
    Session::structs

    Opening new window will automatically open a default subwindow and tab
    if none were specified

Add lib/session_formats
    Add JsonSession, to serialize/deserialize Session structs into JSON
    - add some tests

clang-tidy:
    - fix various warnings
    - disable modernize-use-trailing-return-type check
