[kstars] kstars/ekos: This patch will disable key buttons while slewing to address a problem I have had many times when using kstars, particularly with the align module.

Git commit 6f4da3394457e1e2c97627a136af8119f2fda275 by Jasem Mutlaq, on behalf of Robert Lancaster.

Pushed by mutlaqja into branch 'master'.

This patch will disable key buttons while slewing to address a problem I have had many times when using kstars, particularly with the align module.
I often hit the button before it is ready because there is no definitive indication on the screen that it has arrived at the location.  So I wrote some code that will disable the buttons in question while the telescope is slewing and then re-enables them afterward.
