Iterate and refine send and active transaction behavior
Send is now functional and shows up in active transactions. This involved: - reducing the exposure of the seed - consistently using Ints for blockheight everywhere to match zcash - adding the use of spending keys - adding account initialization on startup - using accounts but defaulting to account 0 - internalizing birthday so we no longer need a reference outside of the library - enabling cancellation during send - cleanup active transaction manager
