Give the devoper some suggestions

TIPS:

- Give the option to save output to source location (program now forces at every start to save in "My Pictures")
- Enable (source/target) paths memory
- Enable batch processing
- Enable Drag & Drop
- I have modified "PhotoLite.xml" with more suitable English dialogs... Get in touch if you want a copy ;)

BUG: The lower part of the "Settings" window (the "Convert" section) disappears after savings the settings the first time (and closing/restarting the program): This is VERY INCONVENIENT because the user might want to reconfigure these specific settings at a later stage and the only way to do so is to edit some registry values... And not everybody knows how to do that!
