getFiles refactoring: kde part

1) kdecommandthread part
before:
getFiles retrieves all files with:
First element = path only of the files
other elements = file names (without path)

after:
Add getSelectedFiles which retrieves all files with their url
getFiles uses getSelectedFiles and truncates to 1 entry if more than 1 entry

2) kdefilepicker part
before:
getFiles case retrieves all files with names including path

after:
add getSelectedFiles case which retrieves all files with names including path
change getFiles to retrieve only the first file (with path)
