System Workbench for STM32

Hi Developer Team,

I think this feature is important. And the process can be simplified to improve user experience (that is what the tool supposed to do right?)

Below is my proposal:

1. Add an icon to Download image in the toolbar so that user is one-click away from reflashing the target if auto download option is unchecked. This is also good if the user wishes to program a few boards, one after another.
2. Add an icon to Full chip erase (possibly with readout-protection-disabling capability) .
3. Highlight with red Probably stale target image message at the bottom most of the debug perspective window frame whenever SW4STM32 thinks so.
4. Replace Load image with Auto download on debugging check-box in the debug configuration to make the intent clearer (optional).
