Bank connections, tokens & account hack

[renatomassaro]

Depends on #239 and #249

• [x] Wire transfer
• [x] Bank token
• [x] Account hack with BufferOverflow attack[1]
  • [x] Overflow on WireTransfer connection
  • [x] Overflow on BankLogin connection
• [x] Token -> Password
• [x] Bank login with password
• [x] Bank login with token
• [x] Login connection
• [x] Bank data on Database
• [x] Bank account logout

[1] - it's not fully implement with Cracker to avoid conflicts with #249. Once it's merged, I'll add BufferOverflow as a module of Cracker, and merge both (like LogForger create/edit).

(Note to self: merging is not a requirement, and if both (file) modules behave differently enough, it does make sense to keep them on separate (elixir) modules)

Incidental:

• [x] Refactor (Hacked)Database
• [x] Major refactor on Support
• [x] Create module's Setup for reliable and integrated game data generation
• [x] Meta data on Connection
• [x] TunnelAction API enhancement with close_connections_where/4

Yeah, this stuff will bloat this PR, but 1) it was a pain point 2) many bank-related tests would need refactor anyway 3) a different PR would depend on this one (and this one would depend on the other PR) 4) just do it

@mememori now that there are a lot of integrated tests, we are getting a high rate of username collision. You might want to prioritize this issue: https://github.com/HackerExperience/burette/issues/4

Okay. Leave it to me

As far as Bank is concerned, this PR is finished. However, I still have to:

• [x] Fix dialyzer errors from PR #239 (elixir bug)
• [x] Rebase/merge master and bank here
• [x] Fix dialyzer error from handling of event CrackerConclusion. This one I've been postponing because it actually needs a refactor on Cracker + Entity, but I'll do on this PR (since this PR makes a complete overhaul on Entity's Database). Nope, I"ll make it on #251, since it's a part of the "SSH path" and I'll certainly have to change a few things on Cracker on that PR. Currently, to work around that issue, I've commented out the whole function (no worries, there's nothing testing that so nothing broke ¯_(ツ)_/¯)

@mememori with that in mind, you can start your review process. Good luck. Meanwhile I'll start Bitcoin Virus (based on this PR).

Edit: My bad, we should review this one only after #239 and #249 have been merged, otherwise unrelated changes appear on the Reviawlbalwerble app.
