Recording: stop recording consecutive duplicates events

A lot of events caught by Exactness preload are repeated with the same
information, such as mouse move on the same coordinates and with the
same timestamp. This adds a lot of noise into the recording file.

This patch checks if the current caught event is the same as the last
stored and skips it if they are the same.
