Added function to skip lines which are not needed for operation: It was not possible in the previous version to skip lines in the top level menu view which were not used for operation. In the past context sensitive menus as well as layout changes have been introduced which cause the cursor to be placed on lines without function. To avoid this it is not possible to mark a line as not in use by enabling / disabling it by the individual meni Id.

User program conditions
The user application to be loaded into the Flash memory using IAP should be built with
these configuration settings:
1. Set the program load address at 0x08003000, using your toolchain linker file
2. Relocate the vector table at address 0x08003000, using the
"NVIC_SetVectorTable"function or the VECT_TAB_OFFSET definition inside the
"system_stm32f10x.c"

can be found here system_stm32f4xx.c
