Add testparser test dependencies

[nohponex]

We should add dependencies to testparser's tests, in that way we can still execute specific using -s argument and any required data from other subdirectories will be executed, exported and then used in the test that has the dependency.

Format:

{
  "meta":{ 
    "dependencies": [
      "user/get.json"
      "account/get.json"
    ]
  }
}

For this, we need to keep track of executed testparser test files in a array (modifications to Binary class).
