renaming of SHA1SUM in iso directory

[Till Maas]

Hiyas,

I want to propose to rename the file SHA1SUM in the iso directory in something 
more meaningful like for example:

FC-7.sha1.gpg 

for Fedora Core 7. It is file with a gpg signature in it, for this reason 
the .gpg suffix and after opening it with gpg it is a file containing sha1 
signatures and therefore the .sha1 suffix. The FC-7 shows directly where the 
files belongs to.

Regards,
Till
