[SternalBoard Update]

Change the main class and the generator of most of the plugin's problems, as its startup is not clear.

Fix:

• Fixed a bug that did not generate the default configuration.
• Fixed a bug that created the update interval in a path that was not the corresponding one.
• Fixed a bug that did not update the scoreboard values.

Features:

• Added comments to the main configuration file to make it clearer with the new options
• Remove stupid classes with inheritance that made no fucking sense (Sorry for the insults xd)
