Allow data exclusion for the server name hash and Windows fixes (#16)

Browse Source 
*   Allows the application path and version to be excluded from the server name
    hash. The following flags were added for this purpose:
      * `SingleApplication::Mode::ExcludeAppVersion`
      * `SingleApplication::Mode::ExcludeAppPath`
*   Allow a non elevated process to connect to a local server created by an
    elevated process run by the same user on Windows
*   Fixes a problem with upper case letters in paths on Windows
