handle_maybe_save_page: prefill with the path improve the download procedure by pre-filling the minibuffer with /tmp/<file-name>. At the moment ``/tmp/'' is hardcoded. Idea from a conversation with hurricane, thanks!

match actual order

move load_url_in_tab, switch_to_tab, new_tab{,_id} to telescope.c

new_tab: allow to add the tab after a current one this allows cmd_push_button_new_tab to open the new tab right *after* the current one, instead that always at the end.

fix redirect & history the reload command doesn't push the current url to the history anymore.

initial support for gopher item type 7

colorize text/x-patch

pretty print help lines

add other-window (C-x o) and allow focusing help buffer

move in_minibuffer too

reorder minibuffer stuff and while there also rename the bogus completing_read to minibuffer_read. To get a ``completing-read'' one has to call enter_minibuffer with the right parameters.

move help to its own file in order to do so, we also have to export some internal variables from ui (the width and height of the window). Not the best possible outcome, but are used only in recompute_help, and can be dropped later. Also, move wrap_page to wrap.c.

push-button-new-tab on relative URLs now works

keep the scrolling during a save-excursion

lazy loading tabs on startup don't load all the tabs when starting up, only the current one. Defer the loading of the others when switching to them.
