There are too many different types of things named "filesystem" in the
GParted code with the potential to cause confusion.  Namely:

    std::vector<FS> FILESYSTEMS
                              Vector of file system capabilities.

    class FileSystem          Base class interfacing to file system
                              specific executables for querying and
                              modification.

    enum FILESYSTEM           Symbolic constants representing each file
                              system type.

Many recent written or re-written functions already used a variable
named fstype.  Rename enum FILESYSTEM to enum FSType to clearly
distinguish it from the other things with very similar names.  Only
changing the name of the enumeration, not the name of variables of that
type too because that is a lot more lines of code and those can be
changed when the relevant code is re-written.
