Upgrade to yaml 0.5 about uap-r

[jayjacobs]

Would having yaml-cpp/0.5.2 and getting this (below) error on install be related to this issue?

internal_UaParser.cpp:53:7: error: no member named 'first' in 'YAML::detail::iterator_base<const YAML::detail::iterator_value>'; did you mean to use '->' instead of '.'?

Update: Yes, I uninstalled yaml-cpp 0.5.2 and installed yaml-cpp version 0.3.0 from source and was able to install uap-r successfully.

Yeah, we don't yet have yaml 0.5.2 support; it's 0.3.0 only. I keep meaning to port it and then forgetting.

Really the ideal is writing this in R-native C++ or C, but how we get there...I have no idea. This codebase is a complex and inherited one :/
