Add support for an "NVRAM Dump" screen in coreinfo (optional), as well as for

Browse Source 
displaying the current date/time in the lower-right corner (optional).

Also, only build/use coreinfo modules which were selected in kconfig. This
makes coreinfo truly modular, and you can save quite a bit of ROM space
by disabling unwanted parts of coreinfo.

Finally, simplify the Makefile a bit by getting rid of MODULES (and only
using OBJECTS).
