Recent bug fixes

Here's a couple of bugs fixed recently:

Drop down showing duplicate tags
- Fixed an issue that caused tags to be displayed twice in the 'Has tags' dropdown list when editing audience or segment conditions.
Undo/Redo function doesn't capture all changes
- We've fixed a bug that meant some of the changes made to a drag and drop template were not captured in the
Undo
or
Redo
stack. This meant that some of your individual changes would have been skipped while using the undo or redo buttons.
