Remove locales from main repository

Extract another repository only concerned with locales:
https://github.com/thoughtbot/paperclip-i18n

A user of paperclip might choose to add `paperclip-i18n` as a dependency
for their application, or copy over the related locale file into their
project.

This is a first step in splitting some parts of the codebase into other
projects. Simple and relevant contributions like new translations might
get lost in the shuffle of dozens of PRs awaiting for approval, that
take time to review and merge.

Locales are a simple enough problem to be handled in an external
repository, where tests for consistency across translations run in less
than a second, and PRs can almost trivially be merged in.

Fix condition to include Schema, using 'ActiveRecord::Base' instead o…

Remove duplication by reusing existing method.

Thank you both for this commit and merge, but I'll revert it: paperclip

something in aruba 0.10.x is breaking the cucumber specs

the name string is used multiple times in interpolation so storing it reduces object creation

this commit primarily uses frozen strings to reduce object creation during interpolation.
the :basename method now uses File.basename(file, ".*") rather than a Regexp. basename may be called multiple times.

by using the attachment name (symbol) and Class as keys we reduce the number of Strings created before hitting the cache

* Regression fix
* Add specs for intermediate_files var in Paperclip::Attachment
