Remote configuration framework: Add ?version# and ?version#bin

[vanvught]

This would make it possible to show the installed firmware details (date and time).

@rbarreiros For the bin, are you happy with just dumping the U-Boot header?

[rbarreiros]

I'd guess so, yes.

[vanvught]

@rbarreiros I've decided to create a much more simpler struct :

#define SOFTWARE_VERSION_LENGTH 3
#define GCC_DATE_LENGTH         11
#define GCC_TIME_LENGTH         8

struct TFirmwareVersion {
    char SoftwareVersion[SOFTWARE_VERSION_LENGTH];
    char BuildDate[GCC_DATE_LENGTH];
    char BuildTime[GCC_TIME_LENGTH];
};
