- Recorrected the module name to Files.
- Added Files::analyzer_name to get a more readable name for a
file analyzer.
- Improved and just overall better handled multipart mime
transfers in HTTP and SMTP. HTTP now has orig_fuids and resp_fuids
log fields since multiple "files" can be transferred with
multipart mime in a single request/response pair. SMTP has
an fuids field which has file unique IDs for all parts
transferred. FTP and IRC have a log field named fuid added
because only a single file can be transferred per irc and ftp
log line.
