Merge pull request #220 from cvrebert/master

"Twitter Bootstrap" is now simply Bootstrap
added appname to .yo-rc.json to generate classes with proper names
removed unnecessary class suffixes
added custom _.classify method

_.classify uses _.titleize which lowercase the string so if the user
chooses a proper ClassName it will not rename properly
