Fix a new error in scrapping explanation
Update python-telegram-bot library
Don't use hdurl for sending images
Sometimes the image is too big and the bot library fails due to that.
Handle dates out of range
Make scrapping more robust
Update explanation consistently with release
Add apod function to the Telegram bot
Refactor code
It creates the Apod class called from every bot and also useful functions. It
seems to be a (bit) decent library.
Add usage of basic functions
Make the first version of the Telegram bot
Improve instructions for installation
Scrap description with links from web page
The API does not give the description with the links, so I had to write a
scrapping tool to get it from the main page.
Deal with invalid dates correctly
Ask API only if not downloaded
Download and save video
It checks the media type and download accordingly.
