This bug prevented the user from applying new font sizes, margins or line spacings to an opened book.
TODO: Fix ugly UI issue with highlighting

Previously, the user could highlight text and unhighlight it, but unhighlighted text would have stayed highlighted until the user would have done a next-page-previous-page movement. This commit fixes this issue.

It has been replaced by https://github.com/Szybet/inkbox-maps

This is to prepare for the new init binary, which is less tolerant than ash.

The font size slider now has 16 levels of different font sizes.
