Parse current default config

[Evanito]

Goal: Check bot's current default.cfg.example for all config options, then parse them and import them into the webpage. Should find config by downloading from https://github.com/BitBotFactory/poloniexlendingbot/raw/master/default.cfg.example. If that fails, allow user to upload config file they have.

Purpose: This will allow the webpage to be mostly autoupdating, as when a new option is added to the default config, the webpage will also be able to update immediately.

Additional notes:

• Coinconfig would need to be hardcoded into the webpage.
• default.cfg.example would need to be standardised into a form that we can parse for:
  • Option name
  • Option description
  • Acceptable answer range (1-20, True/false, etc)
  • Default value
