Ref #5
This commit adds the /getIP telegram command that allows asking for the
current public IP that the bot has stored.
As it is just a working version and the telegram API is not yet
complete, this command is not yet really tested. I need to provide a
more stable version of my Telegram API beforehand because as of now it's
just a mess really, but this will do for now.
Ref #4
This commit adds an active monitoring of the current public IP. If a
change is detected, then a message is sent to the given Telegram
channel. Add a few tests for the main monitoring logic.
