SA/MS Installer dependencies

[Alex Broens]

Jules,
- Seems SA dependencies are added by the MS installer.
why?
This breaks possible SA updates and forces the admin into setup methods 
which *could* cause isssues in the future

The one more noticeably missing are


REQUIRED module missing: HTML::Parser
optional module missing: LWP::UserAgent (for sa-update)
optional module missing: HTTP::Date (for sa-update)

I came across this when I wanted to update an older MailScanner box with 
  the latest SA/Clam installer.

Could you please keep SA's dependencies in SA's installer and not in MS's

thanks

Alex
