Rowanize the demos ...

[dalehenrich]

GemTalk/Rowan#553 and GemTalk/Rowan#555. I've created this PR primarily to discuss what I've done to Rowanize this repo. Besides adding the rowan directory with the Rowan meta data, I've moved the the example packages around a bit and created some packages that include classes that can be loaded into GemStone ... GemStone base does (currently) support SharedPools (SharedPoools are supported in GLASS) ... I also suspect that I've broken the VAST package meta data ...

Anyway, this PR is against the master branch, but perhaps it should be shared on a rowan or gemstone branch until we work out all of the kinks ...

Hold off merging this PR until I merge my latest code into the vast branch of Rowan ... I'm renaming an instance variable in the component from conditionalPackages to conditionalProperties as part of GemTalk/Rowan#554 ... and my life will be a bit simpler if you hold off merging until I've converted these components and merged the code sans conditionalPackages into the vast branch ... I should have the conversion done by tomorrow afternoon ...

It took a little longer for me to finish up my work refactoring the component structure (componentNames and projectNames moved into conditional sections), but with this commit on the Rowan vast branch, I'm finished. I've also updated the rowan_553 branch (cb69685) with examples of the componetNames (emtpy lists) in the conditional structures) ... so you can merge at your leisier
