Ridiculouser and ridiculouser. Apparently stdlib for MacOS doesn't
have an std::move impl, so I had to write my own.

Apparently, our OSX builds do even not support C++14 (or I wasn't able
to make them, despite the compiler flag). This is ridiculous >:(

This is a workaround for Boost 1.56 bug

C++14 whoud have sufficed, but what the hell?
For Turing's sake, 2018!

Chrono literals are used instead of myltiplying ints by 60

Issue #110

Due to mining power fluctuating a lot in testnet it might be useful
to reduce time before difficulty will be adjusted. We won't expect
security risks (this is testnet, after all), but hopefully it will
help us with testing

Issue #110

- More integer arithmetic fixed implemented
- Proposal needs 12 min in testnet to be established
- Final budget submission starts 8 blocks before superblock
- Code refactored

- Some references were changed to const references
- CBudgetDB constructor and declaration were C++11-improved

Exception specifications are deprecated since C++11, so they
have been removed. Old exception specifications are left as
comments beside corresponding functions

Issue #110

Integer arithmetic problem in CBudgetManager::IsTransactionValid()
is fixed
