spelling/grammar suggestions

[valacar]

Hello. I just wanted to offer some spelling and grammar fixes in the docs and readme. I'm not confident enough to make a pull request, so here is a git diff of the changes I made....

https://gist.github.com/valacar/5a5044e7ad100c0649ce06313003c32f

A short overview of changes:

• "overriden" -> "overridden"
• "uses of current word" -> "uses of the current word"
• "but will a little bit" -> "but with a little bit"
• "millis" -> "milliseconds"
• "cursorline" -> "CursorLine"
• "But it can be overriden" -> "It can however be overridden"

I think that's it. Hopefully it helps. Also thanks for making such a cool plugin...really loving it :)
