Merge #904: [Wallet][RPC] Export basecoin transactions to CSV file

d5b00c3 Create exporttransactions feature that exports basecoin transactions to CSV format (supere)

Pull request description:

  ### New Feature
  Add RPC `exporttransactions` to export to a CSV file, similar to the existing `listtransactions` RPC command

  ### Solution
  Added a well tested external CSV library to the project that will make future CSV functionality trivial in the future
  Added the rpc `exporttransactions` command supporting an output filename; and filtering by account, date range, and/or basic piped separated search string

  ```
  exporttransactions (dummy filename start end categories include_watchonly)

  Exports transactions between 'start' date and 'end' date matching 'categories' to a CSV file.
  Note: To export from a specified "account", restart veild with -depreciatedrpc=accounts and
  use this RPC with an "account" argument

  Arguments:
  1. "dummy"      (string, optional) If set, should be "*" for backwards compatibility.
  2. "filename"   (string, optional) The filename with path (either absolute or relative to veild) [default=<datadir>/export/transactions.csv].
  3. "start"      (string, optional) The start date in the format YYYY-MM-DD [default=beginning of ISO8601 time].
  4. "end"        (string, optional) The end date in the format YYYY-MM-DD
   [default=present time].5. "filter"     (string, optional) A pipe(|) separated transaction filter [default=no filter]
     Allowable filter words TBD
  6. include_watchonly (bool, optional, default=false) Include transactions to watch-only addresses (see 'importaddress')
  ```

  ### Bounty Payment Address

  ### Unit Testing Results
  Compare exported CSV with output of existing list transactions command. Should be identical except export CSV shows also sent basecoin transactions which were missing in listtransactions.

  ### Known issues
  - Only basecoin transactions at this time.
  - Pulls 'send' transactions from multi-destination transactions that you are a receiver.
