Debug enhancements

[42Bastian]

• Preserve breakpoints when image/.o is reloaded
• Reload image by key, e.g. ctrl-r
• Lua shell
• multiple disassembly windows (for example commercial IAR C-Spy has up to 4)
• ~memory dump window~
• Lua function to tell the CPU/Core or Debug-class about a label. Allows scanning of custom files symbol files.
• ~no autorun if debug windows are open.~
• ~reset (F3 preferred as Handy)~

Plus:

• F7 ( step over) : If issued on a conditional branch: Breakpoint behind the branch (like Bugaboo). Helps to finish loops.
