Complete rewrite

[ashtuchkin]

This is a total rewrite of this library to make it more manageable and extensible.

Major changes:

1. Modern C++14 with unique_ptr and exceptions (carefully included to avoid code bloat).
2. Introduced a "pipeline" of modules with producer/consumer pattern to help with decoupling, configurability and future testability.
3. Moved all source files to /src
4. Separate "config" and "run/debug" modes of operation. In debug mode, there's ability to introspect internal module state and messages between modules.
5. Validation of config by creating full pipeline and then disposing it, looking for exceptions.
6. Moved from static data allocation to startup-time dynamic allocation.
7. Introduced Timestamp/TimeDelta interfaces to allow changing time resolution and avoiding overflows.
8. To help with user interaction, dynamic and compile-time hashing scheme is implemented that allows comparing words as simple ints.
