Issue: UIU failure using the offlineosdrive parameter

Certain instances of drive letter formats entered in conjunction with the -offlineosdrive parameter are not parsed correctly and cause the UIU to fail.

Code modified to make the offlineosdrive argument parsing more robust.

As a secondary note, DIFx libraries have been updated to the most recent iteration available from Microsoft, 10.0.14383.0 (the Windows 10 "Anniversary" release, build 1607).


On deployed machines only, the Log folder & UIU data folder have been migrated from Program Files to ProgramData.

UIU log files on deployed machines are now located under the ProgramData\UIU directory. Additionally, resources needed by each application are extracted/placed in the ProgramData\UIU\bin directory (temporarily). Program Files is no longer used for any resources or logs.

NOTE: The UIU plug-in for MDT log files are also now located in ProgramData\UIU; other install files remain in Program Files(x86).
