First commit of journey package

This is the first commit to the AUR of the journey package, a blogging
engine written in golang and compatible with Ghost themes.

This package:

- created the user and group "journey" under which the service will run;
- downloads and compiles the binary, as well as downloads the initially
  supplied theme for journey (promenade); and
- installs all files under /opt/journey (attempts were make to split it
  out under /var and /usr with symlinks, but the code at this time
  doesn't properly deal with symlinks in filesystem searches causing
  unusual errors).

This is the core package which will locally build the binary from the
specified version. journey-bin (pre-compiled) and journey-git (latest
releases from the develop branch) are also available.
