Some typos

[ajnisbet]

Leaving these in an issue as per contributing guidelines, let me know if you'd like a PR

• /: "scales to appropriate size" should be "scales to the appropriate size"
• /download: "Read those articles" should be "Read these articles"
• /how-it-works: "InstantClick shows his" should be something like "InstantClick shows its own"
• /blacklisting & /assets-changes: "add it a ... attribute" should be "add a ... attribute" or "give it a ... attribute"

Thanks, you can go on for a PR!

The contributing guideline isn’t clear, what I intended to mean was that a PR for typos is okay, but for anything more substantial than that it’s not.

Should this issue be closed as the merge content is already in base?
