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