Implemented full end-to-end encryption and decryption of an event using trustee public and secret keys. This required modification of the NodeJS crypto server to receive post data from the crypto_rpc py methods and for combining SKs together. Additionally, the new binary voting encoding scheme has been implemented for encryption and decryption of the event. General UI improvements have been made and as well as some other bug fixes
