Flatten directory structure for git submodule inclusion.

[bgshacklett]

It would be useful to be able to include this project as a submodule of a PowerShell configuration repository. At present, this is not possible due to the directory structure.

The command "git submodule add $uri Modules/OutlookTools" results in the following directory structure:

└───Modules
    └───OutlookTools
        └───OutlookTools

OutlookTools.psd1 and OutlookTools.psm1 end up residing too deep in the structure, and Powershell fails to recognize them. Moving these files up a directory and removing the OutlookTools subdirectory would fix the problem.
