Fix to bug in user model that was preventing the organisation association from working (#30) ...

* updated dragonfly max logo height/width to 160px to fit with current max size of DMPRoadmap logo

* 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.

* commented out legacy user.organisation_id method in user model. Each user now belongs to one organisation

* Commented out other deprecated user<-->organisation methods so that they use the user.organisation_id field instead of the user.organisations structure. This needs to be cleaned up and overhauled in the user and organisation models so that user belongs to an organisation and organisations have many users, and any references to the old code need to be updated.

further changes for create plan de-ajax-ing

updated json for guidance_groups so that the organisation id is included for filtering purposes

Removed ajax calls in create project/plan page. It now passes all of the options to the UI and lets the UI filter them as needed. Also upgraded the select2.js script to the lates 4.x version
