* Fix#3790, shares now use the standard FileWatcher class to detect remote file changes using checksums and file system triggers.
* Fix#3895, macOS file selection no longer hangs the app.
* Restore saving of KeeShare settings accidentally removed by 596d2cf
Replaces all string configuration options with enum types
that can be checked by the compiler. This prevents spelling
errors, in-place configuration definitions, and inconsistent
default values. The default value config getter signature was
removed in favour of consistently and centrally default-initialised
configuration values.
Individual default values were adjusted for better security,
such as the default password length, which was increased from
16 characters to 32.
The already existing config option deprecation map was extended
by a general migration procedure using configuration versioning.
Settings were split into Roaming and Local settings, which
go to their respective AppData locations on Windows.

* ShareObserver watches all shares
ShareObserver watches all shares to and considers settings only on
checking for changes. This fixes an assertion when an export group
signal is received, but export was disabled.
* Extend share message in group view
Extended the message for shared groups to indicate deactivate
import/export and errors when the share was not correctly configured.
* When viewing a shared group, the sharing state is indicated by a label
similar to the search label.
* Banner shows on children of shared groups
* When searching, share banner is hidden
* Fixed issue where group/entry information was not updated after change
* Add source folder keeshare for sharing with corresponding define WITH_XC_KEESHARE
* Move common crypto parts to src/crypto/ssh
* Extended OpenSSHKey
* Move filewatching to own file (currently in two related classes DelayedFileWatcher and BulkFileWatcher)
* Small improvements for style and code in several classes
* Sharing is secured using RSA-Keys which are generated on demand
* Publisher signs the container using their private key
* Client can verify the signed container and choose to decline an import,
import only once or trust the publisher and automatically import all
data of this source henceforth
* Integration of settings into Group-Settings, Database-Settings and Application-Settings
* Introduced dependency QuaZip as dependency to allow combined export of
key container and the (custom format) certificate
