Later Initialization Priority?

Currently, the plugin initializes through plugins_loaded at the default of 10, which then runs through some of the core filter hooks. I think it’s pretty common for customization plugins to load using the same hook, with the same default priority of 10, which makes hooking into some of those filter hooks a bit confusing.

Since there are core filter hooks being applied at the default, changing it to 15 to give other plugins initialization wiggle room I think would be optimal.

Any plugins that are already hooking into these filter hooks are initializing at 9 or lower anyway, so as far as I can tell this would just be to make it easier for plugins to hook in at the default priority.
