Add safe UI widget area drawing API 
Make Screen generic over its display kind: Screen<Tty> and
Screen<Virtual>. The latter is for "cached" renderings we want to keep
and copy to the actual screen when the Component::draw() method is
called. Only Screen<Tty> can write to stdout and it needs an stdout
handle.

Add a generation integer field to Screen, that changes each time it is
resized. This way, we can track if "stale" areas are used and panic on
runtime (in debug mode).

Introduce a new type, Area, that keeps metadata about a subsection of a
Screen, and the generation it came from. New areas can only be created
from a Screen and by operating on an Area to create subsections of it.

This way, it's impossible to make an area refer to (x, y) cells outside
the screen generation of its provenance. If stabilised this API should
eliminate all out of bounds accesses in CellBuffers.

meli tools

This crate holds a collection of small binaries used for meli development. Of note is imapshell which opens a shell to an IMAP server for the user to play with.

imapshell

cd tools/
cargo build --bin imapshell
# Usage: imap_conn server_hostname server_username server_password server_port
rlwrap ./target/debug/imapshell "mail.example.com" "epilys@example.com" "hunter2" 143

Example session:

First, the IMAP connections performs its own non-interactive setup:

Then, input is read line by line and sent to the server. You don't have to prefix the commands with a unique ID, that is taken care of by the tool. Example command and reply:

LIST "" "INBOX"
[2020-08-27 17:14:53]["main"] melib/src/backends/imap/connection.rs:717_9: send_command
[2020-08-27 17:14:53]["main"] melib/src/backends/imap/connection.rs:437_9: stream send_command()
[2020-08-27 17:14:53]["main"] melib/src/backends/imap/connection.rs:459_25: sent: M8 LIST "" "INBOX"
[2020-08-27 17:14:53]["main"] melib/src/backends/imap/connection.rs:729_13: send_command ok
[2020-08-27 17:14:53]["main"] melib/src/backends/imap.rs:1241_21: out: * LIST (\HasChildren) "." INBOX
M8 OK List completed (0.000 + 0.000 secs).
