Vanilla Notebook

Small compatibility update introducing some configs to change the positions of buttons.

Now you can go to config/vanilla-notebook/buttons and find 2 files for configuring the offset from the default positions. The first line is the X, the second is the Y I will probably implement a UI to make configuring these easier at some point, but for now you just need to modify it manually.

This fixes issue #50 and makes it so you can use the mod with other mods which have conflicting button positions. Might extend this to the other buttons in the mod - like those in the sidebar.
