#3 Create only one database

[DrkShadow]

As it is now, if you run md5files in a directory, the files database will be created in that directory. This is unfortunate if you want to find only new files in a given directory, rather than rescan the entire filesystem, as every single file would be found and md5'd.

My desire is to have the scripts know about the existence of the md5 database, perhaps through the single filesystem option, and modify md5files to act somewhat like remd5.sh in that it will remove _only_ files in the database matching the current path, and only if they're _not_ found in the file search that is performed.
