Building again. Working towards basic I/O.

* Abstracted CoreDal to ICoreDal in newly created DataAccess PCL
library, which is intended to be shared in just this way. (I had been
lazy not doing this in the first place, but hey...I've been tired after
working hard at the day job!)
* Still working towards the proper way to distribute code using PCL,
SOA, mobile, etc. Brain is still in N-Tier thinking, plus I am wanting
to reincorporate porpGib (which I went back over and it looks pretty
awesome)
