refactored logging in d2loader, d2record, and d2asset (#898)
* refactored logging in d2config, d2record, and d2asset

* asset manager, record manager, and file loader now utilitize d2util.Logger
* added colored logging to d2util.Logger (excluding windows platforms)
* removed mpq file verification from d2config; d2loader handles this
* record loaders now use the record manager's logger for printing info
* added command line argument for setting log level (`--loglevel 4`, `-l4`, or `-l 4`
* added `LogLevel` parameter to config file
* default log level will show errors, warnings, and info log messages
* specifying log level as an argument overrides setting from config file

* fixed log level tests
