[tauruslib-devel] [PATCH] Fix bug-315: solve "dataChanged" name conflict

[Zbigniew R. <zre...@ce...>]

From: zreszela <zre...@ce...>

TaurusModelList class defines dataChanged signal ("new style") which at the
same time overrides dataChanged slot of its base class
(QListView->QAbstractItemView).

Solve by renaming signal to dataChangedSignal at the same time maintaining
backwards compatibility (using taurus.qt.qtcore.util.signal.baseSignal utility
class).
