Update_Docs Does not Scan Subdirectories

[krkeegan]

Update_Docs scans the files in the lib folder and runs perldoc on the files. The resulting documentation files are stored in a user defined folder and accessible from the mh web interface at http://localhost/docs. Update_Docs can be configured to run on a specific schedule.

However, the current code in Update_Docs will not scan subdirectories in the lib folder, namely the Insteon directory. But we need to avoid the extensive non-MH libraries that are stored there in the site***** directories.

A couple questions:

1. Is this still a good feature? [I think it is nifty, but may not be needed as we could just push updated docs to the stable branch as well.]
2. If kept, how should subdirectories be handled? Option 1. Hard code Insteon as a subdirectory? Option 2. Hard code any directory starting with site as an excluded directory?
