Added fix for issues when displaying column headings on the view plans page. Setup and 'Unknown' column heading that defaults to ' - ' but is updateable in the locale files. If there are issues determining the column heading it will use that value

reverted back changes to user<-->org relationship. added missing api and magic strings sections to the other locale files.

Branding changes (#24) ...

- Removed the description field from organisation
- Added a contact email field to organization
- Added an email address validator
- Updated organisation logo upload so that the system will resize the image to the correct height rather than forcing the user to provide a 100x100 image
- Change how the organisation logo is displayed 

* updated organisation edit page's error messages so that errors are placed in the alert text section. Updated wording in locale files to reflect the 160x160 file size.

* removed height and width constraints to logo upload function. Added method that will resize the uploaded logo so that the width is 160px (maintaining aspect ratio) so that the logo fits within the layout properly

* changed logo size to a height of 100 and moved logo so that it appears alongside the DMPRoadmap logo per the current specifications

* Removed description field from organisation. Add contact email to the organisation. Change the way the logo is displayed on the organisation screen.

fixed merge conflicts with fr and de locale files

Fixed issue with link to the terms page in the 'I accept the terms and conditions' link in the sign up section. The link is a part of the locale file, so created a variable called current_locale
