Implement botlist handling

Implement handling of bots.

Some requirements:

• Fetch list of bots (cached)
• Fetch user info (cached)
• Do not store session nor read it!

We could apply another layer of caching, LocMem.

@GregsCode12 I had to quickly put in an optimisation code.

You may continue to implement something less crude.
