Fix issue#5. Implement parameter sets 'Recursive' and 'NonRecursive'

[0xshaft03]

This PR is in regards to Issue #5

The function call at the bottom of Get-xcyclopedia.ps1 is removed.

Parameter sets are implemented so it will be a recursive scan OR a non recursive scan.

There is a check in the Get-FileList function for the parameter set to implement recursive or non recursive scans.
