wish: focus on date when creating transaction

[Vincent Moriaux]

When creating a transaction, the first thing I do is set the date. It would be nice if the focus was set directly on the date text box, the whole date being selected, so I can start typing to enter a new date if needed.

This facilitate the entry, otherwise you need to click the date field, then select the current date to erase it to type a new one. Or use the Alt-D shortcut.
