[CGMZ] Skill Levels - Version Alpha R4

Hi all, today this plugin was updated to version AlphaR4!

This version adds the [CGMZ] Toast Manager integration. This allows you to show a toast window when the player levels up a skill. There is a global toast preset parameter for all skills, as well as a more specific toast parameter for your skills if you want to have different presets for different skills. When both are provided, the more specific toast preset will be preferred by the plugin.

This update also fixes a bug with skill level experience resetting after saving and reloading.
