Fixed C++ Template and added a random wordlist generator

Fixed the C++ template:
- When trying to compile a large payload generated with the C++ Template, the compilers would error out.
-The fix was chunking the payload across multiple variables and concatenating them before decryption.

Added random wordlist generator:
-If not using system32, or /usr/bin/, or providing your own wordlist was what you wanted, I added a feature with the -r/--random flag that will randomly generate strings to use for encryption.
