Allow for a local configuration file outside of the admin/tool/mergeusers directory so it can be tracked by git

[tgmayfield]

Simple change for a configuration file right next to the mergeusers/ directory.

My project is all tracked in git, and customizations that we make to the merging also need to be included. Those can't be inside a submodule, so this allows for another local configuration file outside the submodule.

Hi @tgmayfield ,

Thanks a lot for your contribution. It seems reasonable to provide different ways of loading/overriding default configuration.

However, It seems to me that the patch provided is concrete for your use case, instead of providing a generic way of providing a configurable path.

I can imagine right now of a possible way of providing some settings into the config.php into the $CFG object, like custom setting like $CFG->tool_mergeusers_alternative_config_path or by overriding plugin config into config.php so that a get_config('tool_mergeusers', 'alternative_config_path') would provide a generic path for that. Even though that alternative_config_path setting does not exist for the plugin in settings.php, I think it should work. Actually, I would try this second option in the first place.

I think that a change in that way, for a generic way of searching for an alternative path for a config file would help to include this change.

In addition, the README should be updated to explain this additional way of loading settings for the plugin.

Thanks again,

Jordi
