Perceive is hard to spell and causes errors when typed by bad spellers (i.e. @rivques)

[rivques]

We should rename this. Alternatively, we could just add a function called percieve that just calls perceive and logs the problem.

I wouldn't object to taking a few common methods and making super-short utility versions of them, e.g. Player.p() for perceive, and Thing.e() for emit. Feel free to do these two, and propose others. But I refuse to bake intentional misspellings into the codebase - what would I tell your parents and teachers? :-)
