Gem naming conventions

Don’t use UPPERCASE letters

OS X and Windows have case-insensitive filesystems by default. Users may mistakenly require files from a gem using uppercase letters which will be non-portable if they move it to a non-windows or OS X system. While this will mostly be a newbie mistake we don’t need to be confusing them more than necessary.
