mbuild scan should report existence of any build_script file in the installation directory.

[Gary Dixon]

In some cases, the installer re-enters mbuild and forgets to read in the perhaps-modified build script (.mb) file. It would be helpful if mbuild reported existence of any build script in the installation directory.

A failure to remember to use the read request could be countered as follows:

1.       Invoke mbuild.
2.       It automatically does a scan of the directory.
3.       The scan identifies an .mb file.  When scanning completes, it prompts 
         the installer:
             "Read the XXXXX.mb file?”  

4.       The installer must respond yes or no to this question.
              o    yes: invokes the read request
              o    no:  scan ends as it does now; but it has brought existence 
                        of the .mb file to attention of the installer.
