Merged in develop (pull request #51)

Develop

* Added an extra test to Slewing so that if connected will check with the mount to see if it's actually slewing, which is should have been doing

* Added extra check to ensure that slewing is return true whilst executing one of the ascom slew commands.

* Tweaked the GetSlewing command hopefully this makes the logic function correctly.
Also upgraded the logging to expose whether it's an internal call or not.

* Another slight tweak to the GetSlewing internal call code.

* Fixed problem where the telescope area was in mm when it should be mm squared.  And the driver was incorrect by a factor of 1000.

* Adding more information to the tracelog for get slewing

* Tweaked the code so that the _forceInternal variable doesn't care about if the scope is connected or not.

* Modified the code again, so that the _forceSlewingCount is done last, so that it's at up to date as possible.
