Add configure.ac to the repository

[cbrueffer]

Hi,

it would be useful to add the configure.ac file that the checked in configure script was generated from. E.g. the current configure script specifies the hera version as 2.0 instead of 1.0, but fixing this in there wouldn't address the underlying issue.
