• moved code for de/increasing font and drag&drop feature (content or while holding ⌘ path) to SPTextViewAddition

- two finger zooming gesture is disabled for NSTableView cells
- i.e. all NSTextViews including NSTableView cells inherit these feature
• simplified QuickLookFormat IBActions
- added bin/text storing type to each action
• QuickLook animation set to SP's window middle point
• fixed issue that while having an image in editSheet an attribute change (font/size) in the editTextView destroyed the image data
• fix to allow again drag&drop an image to editSheet
• hide text/image/hex segment controll and QuickLook pull down button if user chose multipleLineEditingButton for non-blob fields
 • disabled NSLog of print result in TableDocument
