Subject: Split binary to booleans (#203)

* replaced old status with 2 flags for unread and starred

* add fields to db, replace int(1,0) with booleans in sql queries, removed StatusFlags class + refactor code relying to it

* add repair step for migration

* again use integer(1,0) instead of bool in sql queries, because of sqlite doesn't support true/false

* add/fix unit tests for new boolean status

* set unread/starred flags as statements in sql

* fixed mysql unknown column items.unread, fixed marking of read items on repair step

* remove unnecessary bool casts

* add empty checks to Items::is* methods

* update migration to use native sql instead of the querybuilder

* don't cast the flags manually, let the api do the work
