Subject: [PATCH] Prevent SelectionRequests from interfering with blinking
 cursor (#173)

Some old clipboard managers, such as greenclip and parcellite,
constantly poll applications with SelectionRequest events, which breaks
the internal timer and blinking cursor. This fix prevents these events
from causing any disruption.

Fixes #172
