Restructure

[RamblingCookieMonster]

Several changes:

• Restructured paths, moving test material to a Tests folder, Invoke-Parallel.ps1 to it's own folder
• Modified AppVeyor.yml to abstract out Pester invocation and test with both PowerShell 2 and the native version
• Added verbose output to testing of branches not named master
• Fixed PS2 test failure that cropped up. WarningVariable was not writing to a variable. Moved Timeout behavior from Warning to Error (seems appropriate? Presumably a timeout is a failure and indicative of an error state?)

Moved to psm1 and back to ps1 due to scope issues discussed in issue #16

Open to flipping things back, let me know if you have any concerns!

Cheers!

Looks like LF / CRLF (line ending change) for me. It's very hard to review such changes, because you don't see the real diff :(

Odd, I'm guessing it was the commit to change to psm1, commit to move back to ps1 (presumably it sees this as removing the ps1 and adding it fresh). Not sure what the right way to do this is, but I can create a fresh fork with existing files so that we only see diff from master to the current state.

Removing and adding similar files counts as renaming. Such changes relate to line endings in 95% of cases. (and to tabs vs spaces in 4%)
