History filter (#329)

* Add history filters, and hotkey toggle

Switch between different search modes to narrow down the history you
want - global search for all history, host for all history from your
current machine, session for the current shell session, and directory
for the current directory

The default can be configured via `filter_mode`

* Update docs

* Add context
