feat: file/directory/function management classes/library

[azubieta]

due MLDE started as modular desktop, a desing patter for file/directory or I/O access must be handled.. but since razorqt and start of the project a new library raised: LibFM-qt:

• https://github.com/lxde/liblxqt for common access file/dorectory and i/o functionality
• https://github.com/lxde/libfm-qt for common core functionality

archived project and let open this issue with links to libfm-qt du today due let of manpowers this are a reinventation of the wheel

ORIGINAL ISSUE:

File System Access

Resposabilities:
* Browse local file system.
* Browse remote file systems supported by gvfs.
* Virtual representation of the computer that conects all the FS mounted.
* Access local and remote files content.

Service Interface: IFileSystemService

[azubieta]

Top level services were implemented [NavigationService, ItemModelService].

a beautifull work.. in desing patterns.. but this isue due discuss in #29 will be changed.. all the file/DIRECTORY (not folder) task implementation now are handled in the magic libfm library (libfm-qt) since PCManFM-Qt ≥ 0.10.1 o let open this due "folder" or best mean directory and file (directory and file are THE SAME) management are handled by a file manger, A DIRECTORY ITS A SPECIAL FILE AS INODE! ...

so the most similar project to implement a file/directory management service are the libfm-qt
let open this issue as a dependency of the #29

libfm-qt : https://github.com/lxde/libfm-qt
NOTE during changes, LXQT project start to implements a semi-modular desing, in the lxqt library.. https://github.com/lxde/liblxqt its not properrty called modular, its more like a service library to common functionality

NOTE: as MLDE implements a modular integration library cppmicroservices LXQT impelments a core functionality library liblxqt
