Merge pull request #2 from mledu/master

Added Beebe_Dark, Raygun low contrast dark, and underwater color schemes
Adds 'Blues.bbcolors' theme
Removed Beebe_Dark.bbcolors, the color scheme file and it's not working properly.
Updated read me file with credit added for the first ever pull request. Two new themes from Michael Le Du, thanks Michael!
Much better Primary custom highlight color. Not so dark, making selected text much more pleasant on the eyes.
Merge branch 'master' of git://github.com/billkeller/BBEdit-Color-Schemes-Pack
