Ref #3
This commit uses a GET query to ifconfig.me in order to get the current
public IP. It also modifies the initialization message to send the
current public IP to the Telegram channel instead of a simple message.
Ref #2
This commit adds a link to a Go Telegram API to send messages to a given
telegram channel provided with a JSON config file. At the moment the
program sends a simple status message to the bot when starting up, but
this allows testing whether the link to Telegram is correctly working.
