#1292 On run/debug the "Select target dialog" is always shown even when nothign has changed

[Andrew Cottrell]

If you are debugging the one project/workspace and do not change anything that affects then the "Select Target" dialog (dlgSelectTarget from select_target.xrc) then the dialog if not shown will speed up the end user's debugging experience and make it seem more professional.

If you need to change any of the options the dialog you can still change them via the "Project->Set Program's arguments..." menu option if you need to change anything.

The flag/data used to determine if the dialog should be shown needs to be volatile and not saved into the config file. The flag/data also needs to be cleared on a bunch of conditions so that the dialog is displayed just in case the end user has changed something. In other words show the dialog unless you can be 100% sure nothing has changed and therefore there will be cases were nothing has changed, but the dialog is shown.

The changes are expected to be confined to the cbproject.cpp and cbproject.h files.
