Create a new store selector and the ability to spend (completeTx) via a Fullstore. 

I have create a store coin selector that can be used to create spends from the full store.  I changed a few things internally so that send requests complete correctly. 

I'm not sure if the wallet side of the functionality is as you expected (the fromBlockStore)?  

Review and suggestions for changes/improvements welcome  :)
Thanks.

1) Update the Full stores to return StoredTransactionOutput's.
2) Created another coin selector (and abstract class that sub systems can implement) to get candidates from the wallet directly via the store.
3) Updated MySQL field blob size .  It's capacity isn't sufficient (if this field is ever use in future).
4) Updated internal objects to be able to cope with a null parent tx (spend standalone outputs).
1) Ok I wasn't sure where this really goes (I'm going with that was there in the code already), but I can move/rename it NP. I haven't looked into where else you can get this info. It's needed when adding to the DB, and it was previously derived by the store (that wasn't the best place either).

2) The ordinal is based on position of definition in java code. It's better not to rely on code order to get id's. It can lead to funny bugs. Someone changes/adds something new (not at the end) and you have world of pain :) I don't mind if this is what you want to do?
