Fixed issue #63 Get-PoshSSHModVersion might miss version differences

The parsing of the $CurrentVersion results in $minorver being an array.
This leads to the comparison later checking both items.  Changed it to
cast the current version to [System.Version] and then compare the
versions based on that type.
