Subject: [PATCH] Close files deleted via file browser
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Files with changes are kept open and only files deleted via file browser actually close. It’ll make sense to also close files which are “moved to trash” (but want to do some refactoring before adding that).

Closes #512.
