Cleaned up the plugin by 100kB!

- Added an hourly vote reminder, which can be configured in the messages.yml and disabled in the /votesettings. A player will get notified if voting was more than 24 hours ago, or if the player is new.
- Plugin updates are now checked hourly.
- All player input (e.g. votesettings) is now handled by multiple input listener instances, instead of one big listener.
- NPC vote stands are now more stable. Warning: you might need to recreate your vote NPC's after updating to this version.
- This plugin no longer uses the seperate simplecommand and customfile package, but one core project. So that all my plugins can be maintained from one central project.
