Jonas Diemer 1eeea5459d feat: Add reading menu and delete cache function (#433)
## Summary

* Adds a menu in the Epub reader
* The Chapter selection is moved there to pos 1 (so it can be reached by
double tapping the confirm button)
* A Go Home is there, too
* Most significantly, a function "Delete Book Cache" is added. This
returns to main (to avoid directly rebuilding cached items, eg. if this
is used to debug/develop other areas - and it's also easier ;))

Probably, the Sync function could now be moved from the Chapter
selection to this menu, too.
