Switch config format to a custom format

[TheTechmage]

Renzoku needs to use a custom config file format due to the fact that CentOS 6
cannot compile due to an API change that has occurred within libyaml-cpp.
The same API change makes it so that renzoku only compiles on Debian Jesse and
later versions only. Which basically means that you can only run it if you've
got the latest and greatest operating systems. This is a big no-no in my
opinion.

Rough Outline of Tasks:

• Build a custom lexer
  • Is it modular (sub-classable, etc)
• Build a tokenizer
  • get_token returns the lexicon (or token?) type
  • get_value returns the value stored within the CURRENT token
• Build a parser, using the tokenizer
• Restructure src/config.cpp to use the custom parser
• PUSH! =D

libconfig handles this now instead of libyaml.

libconfig worked, until I tried compiling it on CentOS 7... Now I'm just going to switch to a whole, home-grown config format. >_<
