Fost 4 release 4.12.09.44431 now out

This release was tagged a bit late, and this announcement is even later — sorry for that. Hopefully all of the good stuff in it makes up for that.

• Removed a dead constructor that does nothing in worker.
• No longer pass on log messages captured during tests. This stops expected errors from being displayed and confusing the test results.
• Added a basic parser for the RFC1123 formatted dates used in protocols like SMTP and HTTP. Only the format produced by the Fost libraries is currently supported.
• The parser lock is now recursive. This means that we can be more aggressive about using it without causing deadlocks. Also removed the parser wrapper that doesn't take a lock so all uses are explicitly forced to acquire the lock at the right time.
• Deliberately leak the thread counter so that it can't be destructed before threads that are terminating in a global destructor get run.
• Added instrumentation for the number of worker threads in use. Also added decrement to the counter implementation.
• Fixed a bug on Windows where the pre-increment would return the old value rather than the new one.
• Dynamic loading of a library now tries with platform specific prefixes and suffixes before trying the name provided.
• Implement JSON casts for json::array_t and json::object_t.
• Allow the use of constant workers (and in_proc) which makes certain thread wrappers more obvious to implement.
• Implement futures with void type for worker and in_proc. We can still wait on them.
• Added startswith and endswith members to the string class.
• Allow time stamps and time differences to be added and subtracted.
• Made time stamps comparable and also added in a new timediff implementation based on the Boost library version.
• Silenced a clang warning that turns up under some circumstances.
• Added configuration for the log level for the stdout global logger.
• Changed the logging DSL for logging JSON objects thanks to suggestions from jeroen Vermeulen.

• The URL parser (string constructor) now acquires the parser lock. This should help stop Boost Spirit failures.
• Changed some log output for the HTTP server to produce JSON objects rather than an array.
• Support the clang toolset in the compile script.
• Removed some dead code.

• Added set to the jsondb::local transaction to update the value of the JSON irrespective of what is already there.
• The JSON DBs backed to disk can be created with a boost::filesystem::wpath instance, not only from a fostlib::string.
• Changed the logic when a JSON DB is loaded so that it doesn't rely on exceptions.
