Split off logging and utils

[Qubus0]

This needs to be merged after

• serialize into ModData and ModDetails  #60

Breaking changes:
Removed:

ModLoader.
mod_log
dev_log

Use the following instead:

ModLoaderUtils.
log_fatal()
log_error()
log_warning()
log_info()
log_success()
log_debug()
log_debug_json_print()

closes #21

probably switching back to the single method and just adding an enum to specify the log type is better

[Qubus0]

Any particular reason for that? That would mean having to reference the enum every single time for logging, e.g.

ModLoaderUtils.mod_log("some message here: %s" % some_value, ModLoaderUtils.verbosity_level.INFO, LOG_NAME)
# and this if you also want the json print included in the same method
ModLoaderUtils.mod_log("some message here: %s" % some_value, ModLoaderUtils.verbosity_level.INFO, LOG_NAME, true)

compared to this.

ModLoaderUtils.log_info("some message here: %s" % some_value, LOG_NAME)

I feel like it's much more concise and better to understand at a glance

well other than that comment, everything seems to be in place and working
