Improve scalability by splitting the distributor cache. Additional cleanup and

generalizations.

- boom/Makefile, dist/dk/Makefile: the "files with everything" are now
  called dist/db/all.* instead of dist/db/digi-key.*
- boom/manu/panasonic/Makefile, boom/manu/stackpole/Makefile,
  boom/manu/yageo/Makefile: changed digi-key.equ to all.equ
- boom/Makefile: there can now be a list of distributors
- boom/Makefile (tar): new target to generate a snapshot of the database
- boom/Makefile (PHONY): added "spotless"
- boom/dist/dk/Makefile: do not merge catalog listings so that we don't have
  to search a huge cache with O(n^2)
- boom/dist/dk/Makefile (clean, rebuild, update, spotless): targets for
  different degrees of rebuilding
- boom/dist/dk/dk-db.pl: added progress report output
