[crossfire] Archetypes collection changes proposal

[Mark Wedel]

  This idea seems reasonable.  The original collection dates back to a time when hard drives were much slower (and amount of memory in systems was less, so likelihood of that data being cached was low)

  Like Kevin, I'm not sure if there is still need for collected archetypes - the tar file could just be distributed as is now, and have it unpacked as part of the install.

  At least for the .arc files, in theory, I think a 'cat */*.arc > everything.arc' would more or less work - archetype files can currently have more than one archetype.

  The issue is the png files - those can not be simply combined - some form of container would be needed, whether that is zip, tar, or custom format currently used.

  One advantage in the past was that having large files was more efficient if you wanted to compress them, but that isn't an issue now days.
