Handle contract constructor inputs

[ngotchac]

Fixes #3314 and fixes #3395 and closes #3393

Try contract deployment with this ABI:

[
   {
      "inputs":[
         {
            "name":"_owners",
            "type":"address[]"
         },
         {
            "name":"_ownersS",
            "type":"string[2]"
         },
         {
            "name":"_int",
            "type":"int256"
         },
         {
            "name":"_string",
            "type":"string"
         },
         {
            "name":"_bytes",
            "type":"bytes"
         },
         {
            "name":"_uint",
            "type":"uint256"
         }
      ],
      "type":"constructor"
   }
]

@ngotchac Will review first thing in the morning. (Have been through the code, nothing critical pops up, however need to pull down and play with this one as well)
