Requirements fixup

[Grinnz]

1. Move the contents of PoeBuildInfo.pm into Makefile.PL, the only place it is used, to remove the layer of misdirection when debugging the build process.
2. Use the -f 'META.yml' hack from Distar to keep dynamic deps from being added while authoring, so that they don't show up in the static deps. This is possibly preventing POE from being installed on Windows, where IO::Tty does not install. Unfortunately without switching to a proper separated authoring tool, this is the best option I can think of for making the distinction between author and install time.
3. Quote versions of requirements, because module versions are strings (trailing zeroes are significant, avoid floating point errors, etc)
