Introduces version string in log message

Adds a version string to enable the user to distinguish between
multiple Prosody-Filer versions. The version information is "baked in"
via the linker in build.sh

 Prosody Filer has no immediate knowlegde over all the stored files and the time they were uploaded, since no database exists for that. Also Prosody is not capable to do auto deletion if *mod_http_upload_external* is used. Therefore the suggested way of purging the uploads directory is to execute a purge command via a cron job:
 
-    @daily    find /home/prosody-filer/upload/* -maxdepth 0 -type d -mtime +28 | xargs rm -rf
+    @daily    find /home/prosody-filer/upload/ -type d -mtime +28 | xargs rm -rf
 
 This will delete uploads older than 28 days.
