don't empty vlist in load_url_in_tab
we already do that a bit after in do_load_url
free page contents on do_load_link
to do that, move empty_vlist to wrap.c and provide a similar function for struct line*s.
implement a side window
atm activable only via toggle-help and renders the defined keys. It's not focusable.
add cmd_move_tab and cmd_move_tab_to
bound to `C-x t m'/`g M-t' and `C-x t M'/`g M-T' respectively, names lifted after the Emacs corrispectives
add backspace (keycode 127), for the linux tty
linux ttys seems to send 127 on backspace, or at least do that under tmux. Educate telescope to treat 127 as del.
big refactor: introduce the window abstraction
- commands now take a struct window* instead of a raw tab - the struct ui_state is gone - using a window for the minibuffer too helps avoid code duplication - it will let us having more than one window on a tab! :DD It doesn't seem to have broken anything...
