Display a better error message if an AV package has deleted an executable file

[Brian Smith]

Sometimes an Anti-Virus package will mistakenly detect a problem in one or more of the executable files (*.exe or *.dll) shipped with the Windows version of POPFile. The NSIS-based programs should display a more meaningful error message than, for example, runpopfile.exe's rather cryptic "Error: Compatible version of POPFile not found!" which will appear if popfile.exe has been deleted by an AV package.

The PFI Diagnostic utility should also be updated to check for the six basic popfile*.exe files and report any missing files (in both reports?)

The initial implementation will only perform these checks when a FULL report is generated.

I decided to make the diagnostic utility always report how many of the *.exe files it finds. See [3180] for details of the code changes made to the utility.

Also need to consider the case where the referenced drive is not available and issue a suitable message instead of just complaining that the file cannot be found. See message:216 for an example of this problem.
