Refactor.

[futhr]

Refactor for master branch. Re-submitting my (updated) pull request (#47).

• [x] Updated engine and gemspec.
• [x] Move settings to own configuration page + add new preferences.
• [x] Compacted pdf.prawn templates to single files with much more readable syntax (now they are easy to copy for custom slips -before it was just plain confusing).
• [x] Refactor test environment + add spec coverage.
• [x] Update all locales to match new structure (:de and :es still need some work).
• [x] Add :sv and :fr locales (the latter need grammar check).
• [x] Update documentation.
• [x] Add LICENCE.md file #62.
• [x] Add Travis and Code Climate.
• [x] Build version with Gem::Version.new + bump gem to 3.0.0.alpha.
• [x] Include new font options from #46.
• [x] Add support config for Hound CI.
• [x] Fix so it hook into v3.0.0.beta + Bootstrap layout changes.
• [x] Still need some misc tweaks for the Prawn templates.
• [x] Add PDF samples and screendump of admin settings in wiki + some guides (when merged).
• [ ] Store dependent settings support.

Note: need to add more tests for prawn templates, but 0 - 96% coverage I believe is a good start.

Not that right side menu need CSS tweak to crop text or it will look strange for languages like German and Finnish (they have longest words). Also its tooltip should go to left not top.

@peterberkenbosch or @JDutil You welcome to press merge if you like the update ;). I have cherry-picked the first 6 commits into 2-4-stable branch. The rest is major rework to move this extension forward.
