Thrift: Added support for double type across all languages

Summary: Just for completeness cause I'm crazy. Let's never use these!

Notes: Also made thrift grammar support # style comments, so you can do this at the top of your files

#!/usr/local/bin/thrift --cpp

/**
 * This is a thrift def file youc an invoke directly and gen code!
