Configs: Introduce Blueprints. Refactor configs in webqtlConfig.

* Introduce flask Blueprints to help with decoupling the various
  modules from the `wqflask/__init__.py` module
* Refactor settings: Create a function
  `base.webqtlConfig.init_app(...)` to handle setting up the
  configurations on the app correctly. Call this function at app
  creation time.
* Move configuration utility functions from `utility.tools` module to
  `utility.configuration` module.
* Use the `get_setting(...)` function to retrieve configuration
  settings from the application.
