4.1.0-Alpha

• Switch from pagination "plugin" to "widget" for Tablesorter. Allows us to update to the latest version of TS (fix #688, #715)
• Implement WhoopsRenderer for pretty debug pages. See (#674)
• Refactor error handling. Move responsibility for displayErrorDetails to handlers, and factor our ErrorRenderers. Addresses (#702)
• Move composer.json to root directory to allow installing UF via composer create-project
• Move sprinkles.json to app directory to make it easier to find
• Eliminate the root theme Sprinkle. Custom styling for the root user is now handled with some Twig logic in the admin Sprinkle (#726)
• Rename bundle.config.json -> asset-bundles.json (#726)
• Reorganize assets (#726)
• Heavily reorganize templates (#726)
• Move request schema from schema/ to schema/requests/ (#726)
• Factor out "system" classes from core Sprinkle
• Refactor overall application lifecycle; move main lifecycle into UserFrosting\System\UserFrosting
• SprinkleManager now better focused on a single responsibility
• Sprinkle initializer classes now use events to hook into application lifecycle
• Support for allowing Sprinkles to register middleware (#617)
• Automatically load Sprinkle service providers (see #636)
• Get rid of "implicit loading" for core Sprinkle - core is now just an ordinary Sprinkle like any other.
• The sprinkles:// stream now represents a virtual filesystem for the root directory of each loaded sprinkle, rather than the sprinkles/ directory itself.
• Separate out localePathBuilder from the translator service. Makes it easier to add/remove paths before actually loading the translations.
• Only present locale options with non-null names.
• Rebased ufTable and ufModal with new jQuery plugin template. (part of #646)

• Added support for the Redis cache driver and refactored the cache config values.
• Added user and session cache.
• Common log file for db queries, auth checks, smtp, errors, and debug messages (#709).
