Update README.md

The word "stand-alone" has been changed to "standalone" to promote more consistency when using compound adjectives. To better reflect its widespread usage as a single term, "home page" has also been changed to "homepage." To properly identify "Swiss Army" as a proper noun, the expression "swiss army knife" has been modified to "Swiss Army knife." To guarantee appropriate hyphenation in compound adjectives, "Platform-specific" has been standardized to "platform-specific."
