Feature Request: Improving the organization of packages distribution (remote distribution service)

Split the recordb distribution into three distributions:

• recordb_m: packages that are software implementation of scientific model
• recordb_t: packages that are used in training session ( TP_xxx, and packages that belong to recordschool archive)
• recordb_u: packages that are utility tools (gengiscan, glue ...)

Expected outcome of this improvement:

• more user friendly in the graphical interface (gvle)
• a first step towards adding metadata to a package (use the field keyword in metada file, to put the type of the package)
