introduced swap file creation in rollout
required some changes to existing source files
introduced global FS_FILENAMES, set in nosfs.init()
modified hdd driver to use the FS_FILENAMES in place of
calls to nosfs.getFatList()
moved file name checking to shell
introduced a defect in delete (added to know issues)
TODO:
fix delete defect
roll out, swap, cleanup
non-preemptive
known issues:
hdd driver create not working in all cases
defective functions in nosfs: get(Used/Free)(File/Fat)Blocks
(this means that the info given by ls, and the mbr data tracking fs statistics are going to be wrong)
