Autocompletion minor tweak
Fix for incorrect default database, when cloning or duplicating collection (#56)

Also, you now can double click on "empty space" in tabbar, in order to open
new tab with the same server/database, as currenlty active shell (it is the
same as pressing Ctrl+T)

This feature can be seen as partially implemented #7.
