Merged in develop (pull request #4)

Develop

* Removed unwanted files

* Adding git ignore file

* Started working on getting the basic communications with the scope working.
    Working on routines to get and set the date and time in the handbox.

* Switched the serial port over to using the .net frameworks serial port.
    Extracted the serial port into it's own class and created a simpler command processing mechanism.

* Implemented AbortSlew and did some code tidy up.

* Forced all code to 64-bit only, will make this 32/64 bit before release.
    Fixed issue in the SerialProcessor when setting the time, makes sure that there's no chance of thread stealing when pulling out the junk messages
    Added ConformanceResult.txt to show the progress of the driver development

* Added code for the site latitude
    and started work on the longitude.

* Added unit tests for reading and writing the utcDate.
    Fixed a couple of defects in the code that was setting the utcDate.

* Corrected Longitude value range

* Added support for UTC offset.

* Pulse guiding support added

* Added SiteLatitude unit tests

* Added unit tests for SiteLongitude

* Added unit tests for the new Pulse guide implementation.

* Added support for AlignmentMode

* Added support for AtPark and Park

* Added support for parking the scope
    Added support for reading the scope Azimuth

* Added support for reading Declination

* Added 5 second timeout for the serial port.
    Fixed problem with the GW command not working on the Autostar 497.

* Fixed broken unit test

* Added support for altitude

* Tidying up resharper warinings

* Implemented RightAscension
    TargetRightAscension
    TargetDec
    SlewToCoord
    and SlewToCoordAsync

* Sorted out the target RA and Dec exceptions to be compliant with ascom.

* Implemented SlewToAltAz and SlewToAltAzAsync

* Implemented SyncToTarget functionality

* Implemented slew to target

* Added support for MoveAxis

* Added support for tracking rate

* Added IFocuserV3 to the driver and made sure that it's registered for ASCOM as a focuser as well.

* Fixed issue with Target RA and Dec loosing precision

* Telescope driver now passes the Ascom conformance.

* Upgraded driver version to 0.1

* Added explicit locks around all sequences of commands.

* Basic implementation of the IFocusserV3

* Focuser passes validation, this makes the code V0.2
