Title: improved fix for #563

This implements an message sent indicator:

yellow message -> trying to send the message
red (default color) -> message successfully sent
gray with red border -> failed to send the message

Note: If the message gets successfully sent but Loqui disconnects right after that and does not recive the sent ACK from WhatsApp, then the message still gets marked as failed. Eventually the message changes to send when Loqui reconnects and receives the ACK.
