- drag filter edges in tx + rx

- [add] added -nospec command line option to prevent the use of analysers when the filter item is in use
- [add] webimage item can now be configured to apply the image to the spectral area, and can implement a slide show
- [change] moved release notes button from setup to the about box
- [change] skin images are resized to button/panel/slider etc instead of relying on tile property
- [change] button clicks are ignored in meter item button boxes that are faded

- [change] refactored code that builds the H/W sample rate drop down
- [fix] inbuilt variables that have name with _double now consider %precis=N%
- [fix] resolved issue where redraw of console controls became very slow after 8thOct Windows update
- [fix] button boxes filter/antenna would not save columns correctly
- [fix] fade on rx and fade on tx fixed for button boxes
- [fix] when in Tx rx1, selecting a bandstack entry will not updated it or attempt to change to it
- [fix] mox & ping ToT now work for times greater than 59 seconds
- [fix] text overlay will now retrieve rx1 and rx2 data correctly
- [fix] setup and other dropdown menus will show if window doesn't have focus and the menu is clicked
- [fix] single cal retries up to 5 times if feedback levels are not suitable. Fixes issue where it would need to be clicked multiple times if tx-att was not where it needed to be

- [fix] crash in IOThreadStop() fixed in netinterface.c if moving between p1 and p2 radios without restarting thetis

- [fix] fixed crash issues when using line_out_start and stop tci commands
- [fix] fixed various midi errors that had been sent in via error logs
- [fix] when engaging rx2 a vfoB update is now always performed which preforms necessary initialisation. Previously this was not happening and sometimes rx2 would show 0.0mhz even though vfob was correct, mostly happened at startup. This is probably not 100% a fix for the 0.0 issue
- [fix] fixed crash issue when swapping between P1 and P2 without restarting Thetis
- [fix] antenna tab is initialised with suitable settings for new databases. This has been broken since early dev 2.10.3.6
