 Since about 6 days ago, Travis CI has failed to go past the
 `before_install` step with this error:
 {{{
 ...
 Some packages could not be installed. This may mean that you have
 requested an impossible situation or if you are using the unstable
 distribution that some required packages have not yet been created

 }}}
 (this is from [https://travis-ci.org/postgis/postgis/builds/50001075 build
 #821], the most recent)

 I'm not sure why this is, since [https://travis-
 ci.org/postgis/postgis/builds/49134411 build #817] from almost a week ago
 did not have that error.

 Note that Travis CI mix a few upstream repos, such as
 http://ppa.launchpad.net/ubuntugis/ppa/ubuntu/ (stable), and
 http://apt.postgresql.org precise-pgdg/main, which may influence the
 outcome of `before_install`, which is unrelated to the actual unit
 testing.

 I've reworked the `.travis.yml file`, which does a few of the following:
  * Switch from DOS to UNIX line endings (see DevWikiComitGuidelines)
  * Tidy it up, add nice breaks and enforce <80 chars width to make it more
 readable
  * Use the [http://docs.travis-ci.com/user/using-postgresql/ PostgreSQL
 addon for Travis CI] specifying version "9.4", bumping it from the
 previous "9.1"
  * With `apt-get install`, organize a few logical groups, remove redundant
 or obvious depends
  * Remove commented out parts since they don't have any context as to why
 they remain
  * Also removed a few `git config --global` and `PGUSER=postgres`
 variables, since I'm not sure why they were set and removing them does not
 appear to alter the behavior
  * Don't bother purging other versions of PostgreSQL or PostGIS -- I think
 they can coexist (unless otherwise proven)

 In the end, I'm not exactly sure what it is with `.travis.yml` in `svn-
 trunk` to throw an error, but the attached `mwtoews.travis.yml` seems to
 fix it.

 Please modify as needed.
