Fix and complete the tooltips of advanced sync options

The advanced sync options had either no tooltip at all (Force Session
Upload, Bypass data preservation, Delay inotify processing) or a wrong
one: Disable upload validation was described as disabling *download*
validation, and No remote delete had a confusing wording about "local
file 'deletes'".

All five tooltips now describe what the option does, based on the
current client documentation, including the cautions that belong to
them: Bypass data preservation can lead to data loss without a
recoverable safeBackup copy, and Delay inotify processing requires
Force Session Upload to be enabled as well.

Fixes #284
