More knockout samples for kosamples

These are more of the samples from the "live examples" on the KnockoutJS
website. I have kept the UI/JS largely unchanged to determonstrate their
inclusion into Durandal.
updates to kosamples styles
updates to twitterClient
style changes to kosamples
adding shopping cart to kosamples
adding grid editor to kosamples

This one was using jquery.validate.js, but did not want to add it to the
bundle mix, etc.  Everything else works as far as binding is concerned.
adding contacts editor to kosamples
adding control type and collections to kosamples

these are the final two samples from the live examples on Knockout
website.

Experimental observation module added.
Some bug fixes and perf improvements to observable.

code...and the configuration needs to be updated as part of that.
Working more on setup of the new mimosa skeleton.
Bug fixes in observable. Added serializer.
Merged latest durandal version, removed experimental
