Main ConvertTo-Zip with a few additions and fixes

+ ConvertTo-Zip, originally created to mass convert CBRs to CBZs
  It will only be avilable when 7-zip is available (7z executable)
  Features: Shows progress, can work recursively (preserving folder
  structure), knows to move completed files.
+ Show-Progress: Shorthand for common progress related output
  manipulation (calculation of completion based on time, or item count,
  and verbose output if needeed)
+ ConvertFrom-TimeSpan: string output from timespan, used by
  Show-Progress
+ Get-Path updated to be more efficient (no need for exception handling)
+ PathProcessingFunctions loads a utility function GetShellSafePath
* Repair-Permissions added some status reporting
