Key rebinding script fixes

Fixes two issues:
-Bindings after the first page were not pointing to the correct remapping entries when actually remapping. Were populating the name and button image correctly, but first item on every page pointed to first item on first page.
-Keybinds were never being saved to file if your action maps all had long-form ("human readable") names defined.
