Fix for March update.

Added "Upgrade / Downgrade only Owner and Team" option. If this option is enabled and the previous two are disabled, both the entity owner and his teammates will be able to upgrade or downgrade the entities. Important: If all 3 options are disabled, everyone will be able to upgrade and downgrade.

• Added "Upgrade only Owner Entity Build" option
• A new parameter has been added to the settings to hide the SteamID in the authentication list if you do not have admin permission.
• Now if you don't have permission to reskin, it will also report that you don't have permission.
• Fixed a bug that allowed you to upgrade a container skin even if you did not have permissions to upgrade with skins.

• Now if you only have the reskin permission enabled and not the upgrade permission, a "RESKIN" button is displayed, since otherwise before you could not exclusively enable this option if you did not want to enable the upgrade.
• The upgrade button is replaced in the item list by "RESKIN" if you do not have upgrade permission.
• Now all items are shown even if you don't have permission (although you have it blocked). If you want to completely disable any option, simply hide it from the config.
• Fixed the list of authorized players in the lockers, it was not displayed correctly when there were more than 6 authorized players.
• Images of: cupboard.tool, hammer, metal.fragments, stones, wood and metal.refined have been added to my own website. Since sometimes some clients had problems with images that did not load from the Image Library itself.
• Added support for Notify and UINotify.
• Added option in config to disable gametip.
• BetterTC now supports the new TCLevels plugin. A button to access the level system will be displayed within the upgrade panel.
• Now makes a call to OnStructureUpgrade in case you have another plugin that blocks upgrading to a certain level.
• Corrected a spelling error.
