* Refactor files in src/client/tabs to new Qt Slot/Signal syntax
* Refactor DeckEditorMenu to use new signal/slot syntax
Add DeckEditorMenu as friend class to AbstractTabDeckEditor since the slots are protected
* fix build failure
C++ does not require compilers to zero-initialize value types, so
depending on the platform (here: Linux), the deck editor starts up with
an uninitialized value in the `modified` flag, which is usually not
zero.
* implement functionality in dlg
* add action to deck editor
* refactor and comments
* is this refactor even a good idea?
* remove the friend class stuff
* reorder
* add option for not annotated
* Generify TabDeckEditor.
* Connect dockTopLevelChanged signals.
* Connect eventFilters.
* Remove comments.
* Fix ze build (accidentally deleted a line)
* Fix some pointer chaining.
* Be a lot saner about some signals/slots, as in, individual Deck Editor widgets now internally determine their CardInfo and then simply communicate this to the DeckEditor
* Lint.
* DeckDock can handle its own menu.
* DeckDock can handle its own decrement.
* DeckDock now notifies the deck editor on deck change, instead of individually modifying menu items and modification status.
* Rename.
* Include pixelmap generator for icon.
* Directly use an AbstractTabDeckEditor as parent.
* Move clearing database filter into signal/slot relation.
