Subject: [PATCH] Parallelize read-posts with pmap

This makes each markup implementation process posts in parallel.

In case of a simple test blog with 4 markdown pages mean compilation
time was reduced from 395 to 330ms. In the experiment I used OpenJDK 8
running `lein ring server` on a 4 core CPU.
