v1.44.4

Fixed

• Custom budget categories can now be found and managed on iPad and other touch devices. The entry point for renaming, reordering and deleting categories was a bare, unlabelled icon above the transaction list; it is now a clearly labelled "Manage categories" button. The rename and delete actions themselves already existed - only the way in was hard to discover (#551).
• Deleting a task works again. A missing import in the previous release made every task deletion fail with an error; the import was restored (#556, #553).
