gptel: Add minimal status indicator via mode-line-process

Browse source 
* gptel.el (gptel-update-destination, gptel-use-header-line,
gptel--update-status, gptel-mode): Improve status messaging when not
using the header-line.  When the user option
`gptel-use-header-line` (renamed from `gptel-update-destination`)
is set to nil, we use `mode-line-process` to report on in-progress
requests, and show the active LLM (model) otherwise.  Error
messages are sent to the echo area.  Close #9.

* README.org: Change `gptel-update-destination` to
`gptel-use-header-line` and tweak description.
