Saves a backup of the config after validation in the database so it can
be checked.
To Be Done: Validation of the config when it is loaded against the
database version.
Added the concept of an adapter class that would convert the YAML input
to the setting type and value.
I included an example adapter class for Enum.
I fixed a number of the settings to match the config/yml or the other
way around.
After compiling and running, do /bsb reload to see the result.
This is a WIP and obviously not finished.
Worked on PluginConfig.loadPluginConfig(). Changed the NotSetup
processing : when loading config, it will store errors and if there are,
it will run the plugin as "NotSetup" and send to users what is wrong and
why. Major parts are still remaining as it is a "preview" of an
unfinished and "waiting-for-improvements" work.
