Add function to get the total xp points the bot has.

[zisis912]

Unlike its title, the bot.experience.points property does NOT provide one with the xp points the bot has, but rather its score, displayed only when one dies.

This PR adds a function that does precisely that, correctly get the bot's xp points.

That of course would make the .points property useless, so I would suggest you accept #3125 too if backwards compatibility is not an issue

[rom1504]

actually fixed

please add this function to the doc

[rom1504]

@zisis912 would you like to finish this?

[zisis912]

I am a bit busy yhese days, maybe in a few docs i will get around to making docs for all of my PRs so they can be finished.

[zisis912]

@rom1504 sorry but I really cant get myself to write documentation for all that stuff, however I would like to mention that

#3121 is an absolute dependency for this so I would urge you to merge it

[rom1504]

If you can't spend 5min writing what this code does in the md file then I guess this is not really needed

If you feel otherwise, re-open with the missing doc
