C++ GET/POST, Diceapp and python diceapp

C++ GET/POST, plus diceapp. Also added READMEs for all sections with how to install/use the libraries used in the programs.

I like this `if (curl)` statement - error checking is good.  Only problem is that if this condition fails, there's no output to the user that this did fail - the code will just sort of finish here.  Should add an 'else' to this if and print something simple to the user so he/she understands that this failed.
