EXTRACTION and ARCHIVING

Added semaphore to improve performances, optimize system's resource usage, and increase reliability operating on multiple instances launched from system's context menu

"Extract here" and "Extract here (in new folder)" function uses semaphore to schedule one job at time, password requests are prompted at once to optimize user's time usage and don't interrupt scheduler's work
"Extract to..." function, that already creates a single job queue, can operate in parallel to the semaphore when it is needed by the user to launch other independent jobs
Main extraction parameters are reported in extraction interface's form caption and on drag and drop information box
