1.0.4 driver release

Hi all, We've just tagged 1.0.4 release of the UmTRX host driver. A short summary of the changes: * Do not add 'g' to a git id when creating a version string. * Proper debianization. * Add ability to set diversity switches position from UHD args. * By default route each Rx channel to it's own antenna. * JSON API to question/control property tree of a running UHD app. Useful for querying sensors and for debugging purposes. * Python utility to query VSWR from a running UHD app in real time using JSON API. * Fix DC and IQ calibration utilities. Binary build for Ubuntu will soon be available from the MyriadRF PPA. -- Regards, Alexander Chemeris. CEO, Fairwaves, Inc. https://fairwaves.co
