Subject: [PATCH] monitor: Fix printing of ct objects

Monitor output is supposed to be single lined without tabs, but ct
object were printed with newlines and tabs hard-coded. Fixing this
wasn't too hard given that there is 'stmt_separator' to also include
semi-colons where required if newline was removed.

A more obvious mistake was position of object type in monitor output:
Like with other object types, it has to occur between command and table
spec. As a positive side-effect, this aligns ct objects better with
others (see obj_type_name_array for instance).
