Black magic probe issue #183 (#196)

* In support of 'issue' #183 - Add Black Magic Probe (BMP) upload method
This is basically a merge of work done by @rogerclarkmelbourne in arduino-nRF5-customised, with the addition of bootloader uploading as per @sandeepmistry openocd reference in platform.txt
Note: This incorporates changes based off feedback from @sandeepmistry, @dmikhalsky, @dlabun
* README.md - BMP driver installation details
* platform.txt - BMP tool setup
* programmers.txt - Add BMP as a programmer option

* Update programmers.txt

Remove accidental references to sandeepmistry:openocd for openocd methods

* Update programmers.txt

* * rename bmp programmer to the more descriptive blackmagicprobe

* * remove accidental addition of bootloader.tool to openocd methods

 __NOTE__: To roll back to the original driver go to: Device Manager -> Right click on device -> Check box for "Delete the driver software for this device" and click Uninstall
 
+###### Driver Setup for Black Magic Probe
+1. Download .inf file drivers from [blacksphere github](https://github.com/blacksphere/blackmagic/tree/master/driver)
+2. Plugin Black Magic Probe
+3. Point the installer to the folder containing blackmagic.inf
+
+__NOTE__: If using Windows 10 or Linux then two UART COM ports will be visible without requiring additional drivers

 ### Selecting a SoftDevice
 SoftDevices contain the BLE stack and housekeeping, and must be downloaded once before a sketch using BLE can be loaded.
 The SD consumes ~5k of Ram + some extra based on actual BLE configuration.
