Fix dolphinpart context menu so that the delete/rename/send to trash options are disabled when the directory containing the selected files/dirs is not writable.

CCBUGS: 161594

Issues remaining: Send to trash should be disabled on remote files (and replaced with delete) and edit menu of konqueror still has the actions like cut/delete/rename always enabled.
