New module to search for files on disk by hash

Get-FilesByHash.ps1 accepts a hash (MD5, SHA1, SHA256, SHA348, SHA512, and RIPEMD160 supported; SHA256 by default) and optional base search paths. It then enumerates the files under the base paths, hashes each, and returns an object containing the full path to any files that match.

Fixing merge conflicts.
Fix merge problem with Kansa.ps1.
Modified Modules/Disk/Get-FilesByHash.ps1 to use workflows, but it's not outputing any data.
Fixed the output issue (thanks, @davehull for finding my bug). Now, however, it's pushing out too many lines. :/
Fixed the output of multiple blank lines.

The lines appear to have been caused by threads that did not find a match.
Still have an issue with versioning as PSv3 and PSv4+ behave differently when
returning arrays from a workflow.
Adding comment about SysWOW64 redirection.

Tracking the fix for this in issue #42 in davehull/Kansa.
Modifying %windir%\System32 comment.

@lanatmwan provided a link to an MSDN article providing a workaround, so I updated the comment.

Multiple changes and improvements.

 - Added check for support of workflows.
 - Added single-threaded option for hosts that don't.
 - Added .SYNOPSIS block.
 - Other docuemntation changes.
Removed unneeded options that would have caused errors.
Trying to fix output bug tracked in issue #2.
Going to stop letting the perfect be the enemy of the good.

Per @davehull's advice, I've fixed this so that it works, even though
it's not exactly how I wanted to do it. Tested on 3.0 x64 (workflow) and
3.0 x86 WOW (function). Will test on 4.0 x64 after commit, then merge
into my master and submit a pull request.
Moving OUTPUT directive so .SYNOPSIS block works.
Updating master to match upstream.
Hopefully fixing the long-running merge conflict with kansa.ps1
