Fixed Vulnerable Vote Function

[Ronnieraj37]

Description

Fixes #15

I've fixed the Vulnerable Vote function which allowed attackers to loop the function to execute indefinitely. Additionaly :

• Removed the Voter function as it was repeating the castVote functionality
• Added getUserStatusForVote from the Authentication Instance in Election.sol
• Added a modifier of OnlyOwner in Ballot Contract to ensure only the owner can Vote
• Replace the _voter in ballot.vote(_voter,_candidateID, weight,voteArr); with msg.sender
