Update to use bundler and work on Ubuntu Trusty.

Switching to bundler saves confusion about gem paths when running
sass/compass to compile the CSS.

Trusty can use precisely the same packages as precise, with a few tweaks
to generalise the contents.
Remove liberror-perl and libsoap-lite-perl.

Try and save other people the potential pain of installing SOAP::Lite;
only UK FixMyStreet and Zurich geocoder use it, so set it as an optional
feature in the cpanfile instead.
Remove unused variable.

Also, s///r isn't present in 5.10, and FixMyStreet should still install
on squeeze.
Reinstate some cpanfile.snapshot entries.

This puts back any missing snapshot modules removed in
1708bc30af7176f95f0ec5718289d3a633daf32b, as they are required for
installation on squeeze, which misses or does not have the required
version of these.
Merge branch 'trusty-tahr'
Switch graph generation programs to Perl.

This means they access the database the same way all the other scripts
do, preventing any issues due to different setups. Also tidy up state
grouping in graph, add Norway start date.
[UK] Change most prominent "Get in touch" wording.

With reference to #922, to see if the more 'businessy' phrase makes any
difference.
Update graph crontab lines to use wrapper.

After the changes in b3c664b, these two lines need to be called with the
cron-wrapper.
