EN minor grammar fixes, corrected typo in README.

[AwesomeTornado]

There were a few strings with confusing grammar consisting of a question being used as a statement.
I think it's called a subject-auxiliary verb inversion? I'm not a linguistics major though, so I'm not sure.

Example below:
Old version:

• this controls when is [something] changed
  New version:
• this controls when [something] is changed

Additionally, I fixed a minor typo in the readme, and a few instances of confusing wording. These are minor changes but should make things easier to read and understand.

Native English Speaker(British), yeah these changes are better.

Now there's nothing wrong with this, it is just an observation and not a complaint. I actually find it really interesting. These strings appear to originally be written by Froox. This makes sense, as some of the grammar choices here are common for non-native English speakers. As I said, nothing wrong with this, I just find it interesting!

That is interesting, I had assumed that they had been written by a non-native English speaker, and looking at the Czech language (I think that's Froox's native language), it makes sense actually. Czech has a different "default" sentence structure.

Also, I totally agree that there is nothing inherently "wrong" about mistakes when using different languages, and I highly recommend this fascinating article talking about them.

This looks good, thank you for improving the language! Merging in!
