batch processing: path entry should be easier

[jfd]

1 It should be possible to type or copy a path;

1b or even to draganddrop from WinExplorer

2 The output path should default to the Input path, to be edited

2b or maybe to a (parametrizable) standard suffix of it,
e.g. if input is specified as c:\photos\playa
output could default to c:\photos\playa\vignettes
(which can be accepted or edited)

don't forget you can save your settings, don't need to set every time your folders
