Mainly a bugfixing and tidying-up release.
- program is now multithreaded, so responsiveness isn't degraded during sampling
- added 'System uptime' figure and option to use AS or SF for DSL uptime
- corrected wrong positioning of some buttons
- changed layout of QLN/HLog pages so that resizing doesn't cause components to overlap
- increased minimum size of window so that resizing doesn't cause display problems
- corrected scaling of SNR per tone graph
- corrected issue when pausing in the middle of a sampling period
- 'Sampling' is now displayed during the initial sampling period (although not really necessary any more)
- corrected issue which gave error message "The internet connection may have been dropped"
- sorted out enabling/disabling of the Start/Pause/Stop buttons to reflect status
- changed code which detects VDSL2 band plans, to take account of systems which don't use band U0
