First round of cleanup ahead of migration to 2.x
[#3] Added .gitignore for front end files
[#3] First working version of new front end
Add scripts for DB migration

* groups_to_ogs.sql: transforms groups into orgs and assigns datasets to
  orgs

* users_to_members.py: adds users to the members table according to
  their old group roles so these are moved into the relevant
  organization
Add a .gitignore file
Add file for new plugins and first stub of the publishers plugin
Add first draft of IDatasetForm

Adds just the filetype and country fields and the form fields (probably
in the wrong place)

TODO: * add rest of fields from package_iati.py to the schemas
      * add rest of fields to form (single page)
      * add rest of needed helpers
[#3] Header now looks as expected (user area needs some work)
Merged ckan-2.x
[#3] Account area in header is now complete
[#3] Upgrade to bootstrap 3.0.0 and better general styling from CKAN core
Remove strip from validators
Add strip to converter; remove unused converters
Add the whole schema to Publishers plugin
[#3] Adds footer to site
[#3] Homepage is nearly complete
Move dataset validators order

_ignore_missing should be executed first otherwise the rest of
valiadators can fail if the field is missing.
Further work on the Publishers form

Finish schema for form to db and viceversa, add fields in templates. Add
helpers.
Add redirects for publishers

We can not handle it via IGroupForm, as we will lose the
group_type=organization property, so we need to explicitly set redirects
and mappings to map org actions to the organization controller.
Cleanup schema a bit
