Added drop zone for revealing encrypted files or folders (#2592)

* Added drop zone for revealing encrypted files or folders

* Split god drop zone into distinct drop zones in vault list and vault detail unlocked

* Prevent cursor from changing if content doesn't match during drag over

[ci skip]

* Removed unused methods / css classes

[ci skip]

* Updated method name

* Refactor Vault::getCiphertextPath to only accept strings starting with "/"

* bump cryptofs

* ensure that path cleartext path always starts with "/"

* added file chooser for revealing encrypted items

* Trying to fix path parsing again

* Updated drag & drop design for buttons

* use RevealPathService to reveal files in file manager

* fix compilation error

* Copy paths to clipboard if no revealService is present

* reintegrate wongFileAlert

* Only accept TrasnferMode.LINK

* updated drag-n-drop button styling

* added tooltip

* updated string

* cleanup
