Preparing 2.0.0 release

No longer a header-only library. Added support for src files to make …
…it simpler to integrate with dynamic libraries with hidden symbols.
Added .cpp files to hold thread pool and pre-exit support code to avoid duplicates when built as/in a DLL.
Declared pre_exit and at_pre_exit as extern "C" to make them simpler to export from a DLL in an export list.
Adding an issue to make it simpler to export the default executor as well.
