Subject: [PATCH] Replace server-side dnd validation with client-side
 validation: (#368)

* Replace server-side dnd validation with client-side validation:

Client-side validation means:
* Custom widgetset is used to introduce the client-side validation
* Accept-calculation is performed on client-side
* Drop-hints are calculated on client-side (show/hide)
* Row count decoration is calculated on client-side (multi-selection)
* Notification box is triggered from client-side

Beside the migration from server-side validation to client-side
validation there are few improvements:
* Improvement1: If drag is aborted outside the components by releasing
the mouse or the drag aborts by pressing the ESC key) -> drop area hints
are removed
* Improvement2: If multiple rows are selected in table, but drag is
performed on a non-selected single element from table -> the single
drag-element is not decorated with the row selection count
* Improvement3: Upload View: Component 'Drop files to upload' only
accepts files (and no drags from filter and software module component)

* Improve code quality

* Fix formatting of license headers

* Fix scopes and modifiers

Signed-off-by: Marcel Mager (INST-IOT/ESB) <Marcel.Mager@bosch-si.com>

* Externalize key-strings used for dnd-data transfer from server to client

Minor issues:
* improve naming schema of control variables (no more i-s)
* add final modifier

* Add license header
