sorta fixed bug with sleep and timing where interrupting

dwmblocks by clicking on the bar would interrupt the sleep causing it to
reload everything sooner than it should, which would cause slower things
to not update and disappear untill they were reloaded. This was
especially a problem with using scrolling on blocks.  Still occasionally
breaks but is much less horrible.
