Start with making commentaries pages responsive.

Start transforming the prefill with Arxiv commentary request
 to a class based view using the Arxiv caller.

Alter ArxivCaller to inheriting from BaseCaller
 and slightly alter the caller workflow. This
 prepares to be able to use ArxivCaller in
 for example Commentaries as well. Further
 initiate empty DOICaller which should
 be used to do similar work but with a DOI.

Prepare ArxivCaller to be used in multiple models.
 It includes the creation of a ArxivCallerMixin in the
 behavior file which should be used in all objects using
 the ArxivCaller.

Move ArxivCaller to the scipost folder, since this caller
 will be used by more apps, such as the commentaries
 apps.

RequestCommentary is transformed to a class based view. Further
 moved strings to `/strings` and used django.messages middleware
 to pass messages to the user instead of context data.

Remove management command which does work you should
 actually do in the admin area.

Release 20160202

Potential NotDefined raise if type is neither a
 `test` nor `deposit`.

The string method is not returning the right
 fields.

Syncing all master changes into release branch to
 make sure all changes won't be overwritten on merge.
 Also improving PEP and wildcard imports directely in
 some files, since this caused some NotImported errors.

Conflicts detected by Git:
	.gitignore
	scipost/models.py
	static/scipost/SPB/SciPost_Supporting_Partner_Agreement.pdf

If a user wants to change its password, but does not
 submit a valid form it still gets a 'Succesfully changed password'
 message.

Due to potential data loss during migrations
 with the use of `auto_now`, it is recommended
 to write create a custom auto-now-field.

Creating a new ThesisLink didn't save the `requested_by`
 field, causing trouble in for example the vet view
 for these specific objects.

Improve the templates using template tags.
 Further, wrapping the `content` block in the
 `container` div element.
