Subject: [PATCH] Add a button that pick a random manga to read (#876)

* add random button functionality

* Add random manga setting, this should close #873

It open only manga with unread chapter, if we feel is needed we could add a setting to open even read manga

* Add random manga functionality to hopper long press

Also revert previous changes to preference and ui
