#31 Convert Database to Diffable Format

[Luke-Jr]

This patch modifies LambdaMOO (patched with db_options) to
convert a normal database file to a readable, diff-able format.
An example use would be to compare changes made between an
old and new core to patch an existing MOO based on the old one.
The convertor will *only* write to files ending with .moo, to
prevent accidental overwriting of the real database (which will
usually end with .db or .db.new).

The patch is missing the one new file. Will add soon. (I deleted the
development dir after making the patch, so I may need to rewrite it)

Fixed and made a new patch including the missing file (which I had to
rewrite).
I also added a bit not in the original:
- Output is more diff-friendly, using player names when possible and
reducing objid references (since obj #s often change in core releases)
- diff-db script to automaticly convert two databases and run diff on
them. Syntax: diff-db one.db two.db [diff-options]
- diff-db will remove object_size properties since they will often change
without anyone caring

diff_database_conversion for GammaMOO 1.8.1g2 w/ db_options

Another version of the patch. This one is designed for GammaMOO, but
might apply to other patched-up MOOs. Either way, both of them
together should be a good reference for someone wanting to port it to
their patched server.
