(maint) Add Travis CI support to active branches

Without this patch all active branches do not have proper Travis configuration
files.  This is a problem because Travis will exercise any branch pushed to the
puppetlabs organization repository on Github.  The default behavior is to email
notifications which is undesirable.

To address this problem Travis configuration settings are added to an active
branch.

Active branches are those that have recent activity when compared against the
following command:

    for k in `git branch -r |grep origin/|perl -pe s/^..//`
    do
      echo -e `git show --pretty=format:"%Cgreen%ci %Cblue%cr%Creset" $k|head -n 1`\\t$k;
    done | sort -r | grep origin

Which should produce output like:

Relax gem dependencies on Facter and Hiera

Without this patch applied an older version of Hiera is
automatically installed as a dependency installing Puppet.  This is a
problem because there are important bug fixes happening in later minor
versions of Hiera.  The same is true of Facter.  The cause of the
problem is a tight specification of `gem :hiera, "~> 1.0.0"` which means
"greater than 1.0.0 but less then 1.1.0".  1.1.2 is the current latest
bug fix version of Hiera.

This patch fixes the problem by relaxing the dependency to "~> 1.0"
which means "greater than 1.0.0 and less than 2.0.0"
