allow to re-open closed tabs
Save closed tabs to a "killed tabs" queue, for up to a max of "max-killed-tabs", and allow to re-open them. Keep the tab history but not its content. This integrates nicely with the session file, just add the "killed" flag as alias for TAB_KILLED and put it in the ktabshead queue upon initalization. It's thus possible to re-open closed tabs even after telescope has been closed, and tabs keeps their history! Add a new cmd, cmd_tab_undo_close, to try to re-open the most recently closed tab and bind it to `u'. While here, add a TODO for the tab history memory leak.
de-quirkify execute-extended-command
On RET, execute the command on the selected line rather than what the user typed. This saves a TAB (to expand the entry) and is more in line with the other completion commands.
replace TAILQ_EMPTY/INSERT_HEAD/TAIL dance with a single TAILQ_INSERT_TAIL
Now that all the queues are correctly initialised, there's no need for that dance.
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.
