cowdb1.1

CowDb is perhaps (hopefully) complete now. Release 1.1 was all about finishing touches.

• Handle code is now easier to read.
• Footprint on disk has been reduced.
• Symbolic references are faster to resolve, thanks to the use of direct pathnames.
• And a bug fix in multi-node b-trees has been made. (I believe this bug was introduced in 1.0.)

So if all goes well, I can now focus on COODBMS and JOODBMS. I am especially excited about dynamically creating the various elements of a Rolon, as this will reduce the footprint of the less-developed rolons as well as adding making the sample output easier to read.
