Pre-Second Draft

New
---
* rottDB_copyall and rottDB_moveall functions are added

Changes
-------
* rottDB_copy and rottDB_move functions now have an "overwrite" argument
* Some improvements

(Possible) Bugs
---------------
* When you try to save/load a database than contain a/many key(s) or value(s) that contain newline('\n'), probably you will get an error while loading.
  It's because, rottDB_save and rottDB_load functions use newline to seperate keys, values and metadata. I have to find a proper way to save them.
