1. Added a new Tcl procedure to the content repository's library, named cr_write_content, which properly writes content to the connection regardless of RDBMS and storage type. This simplified a bunch of stuff (which explains the removed files).
2. Fixed a lot of general comments issues regarding HTML vs. Plain/Text, attachments, etc.
Big 'ole update to implement multi-db aware packages. Don't try this yet, I can't *possibly* have gotten all the right files added and removed in one fell swoop!
