'make install' installs docs in incorrect directory

[levitte]

Hi,

I just noticed that make install installs extra documentation in /usr/local/share/makefile2graph when I would have expected it in /usr/local/share/doc/makefile2graph:

install LICENSE README.md screenshot.png /usr/local/share/makefile2graph

I assume that is was a simple mistake, resolved like this:

diff --git a/Makefile b/Makefile
index 1e1fb81..33394aa 100644
