No longer appends timestamp to default_url when job is processing
Merge pull request #10 from ScotterC/custom-processing-url

added option to add custom reprocessing image
Update lib/delayed_paperclip/url_generator.rb

Found this was necessary because not all images have delayed_options but will still be affected by the url_generator.
Merge pull request #11 from endoscient/master

Don't append timestamp to default url while processing
Updating .rbenv-version, re-ran the tests with some newer stuff.
Updating gemfile.locks
Support sidekiq
Merge branch 'sidekiq_support2' of https://github.com/dtaniwaki/delayed_paperclip into merging-sidekick
Fixes #15
Releasing 2.5.1.0, with the following new features:

- sidekiq support. Thanks @dtaniwaki!
- other odds and ends, nothing major though.
Allowed nil files to display default_url when they are not processing, and their file is nil. Added test case to support previous functionality as well as a new case to verify that this feature works
Merge pull request #19 from FulcrumTechnologies/master

Use default_url when no file is provided or is not processing
Support only_process option to process_in_background

Paperclip::Attachment.reprocess! doesn't use the only_process option
set by has_attached_file.

By default, reprocess! will delete and rewrite every style, including
:original, which is unnecessary if you're just creating thumbnails.
Add :only_process option to README
Merge pull request #21 from jakepaul/only_process

Support only_process option to process_in_background
use only_process from paperclip options first, override if delayed_paperclip specifies
