Add synchronization between node and clive

• Moved NodeData to Account
• Synced data is avaiable on Cart and Dashboard
• Refreshing data is completly separated from fetching data from node
• Refactored communication threading: Now there is one thread pool, so it does not starts worker thread on every call, which is faster.

TODO:

• Add support for rc
• Add rc calculations
