Reworked the config_reader interface a little to make it easier to use. In 

particular, I removed the enumerator over blocks in favor of a simple
get_blocks() function that just returns a std::vector of all the blocks.
I also removed the requires clauses on the block and key accessor functions
and instead made a request for a non-existent key/block result in a non-fatal
exception.  This way users can let the config reader perform a more natural
role in config file validation (by catching this exception and acting accordingly).

(i.e. returns the name of the block that the enumerator is currently at) config_reader's block.
(i.e. for all strings str in blocks it is the case that is_block_defined(str) == true)
