[WIP] Changed spelling on cancel (#90)

[RLittlesII]

Resolves #90

[glennawatson]

Are we doing American english or British english? Seems single L is American english.

This is something that came up before when I was editing one of Geoff media announcements, eg which form of English we should use since he was using Australian english. We should probably document a standard in that regards.

[RLittlesII]

I am not sure which version of English we should go with. In this specific instance, it is odd (and I've had this conversation with other devs) that the .NET Framework delivered CancellationToken is spell with two l's, but everything in the file that references cancelation is spelled with one.

That said, I'll defer this until we verify what our standard English will be, but I think that is a horse of a different colour. 😉

This is waiting on reactiveui/rfcs#11 to resolve.

[glennawatson]

This has changed so much since you've done that due to @worldbeater changes, should we take this up again in the main documentation?

[RLittlesII]

@glennawatson I am going to close this, as the RFC is leaning towards leaving the spellings the way they are anyway.
