gif 0.2.0

• Added support for uploading images to imgur—gif upload. Due to rate limiting, you have to configure the API key yourself in the config file though. Here's a minimal .gifconfig file to enable it:

{
  "Upload": {
    "Provider": "imgur",
    "Credentials": {
      "ClientId": "your client id"
    }
  }
}

• Added a tag listing command—gif tags.
• Added a filter for local images.
• Added the ability to print out map-based config values.
• Fixed filtering by making it look at tags even if passed a hex string.
• Fixed column formatting in listings.
• Fixed crash when trying to import a directory with extensionless files.
