Added examples:

* btcsimple: the 24 line bitcoin server - closes bitcoin#12
* ponzicoin: An example of an alternative chain, this one is a fast forward of bitcoin to easily study long term effects. - closes bitcoin#11

Build example using ccmake - first configure ('c') then scroll down to enable examples, then configure again and then generate and exit. Default is to build without examples.
