Make sure the resource read does not break because of scraper_icon
Fixes 224

Refactored the WDTK url in the publisher extras to be foi-web both in the
publisher extras (and named the same in dataset extras).
Updated package_create auth function for #59

- Makes sure the group in the package data_dict is '' and not ' '
- Allows publishers (in a group) to succeed in the auth call if the
  group name for the publisher is not set - it will be caught by
  validation.
Cleans up the error block to stop keys AND values appearing as list items
#243 Four out of five test datasets pass validation.
#210 Selenium test minor changes: Logging in setup now works. Finds selenium config now whatever CWD. Moved to testselenium alongside normal tests, instead of in testtools folder - feels better. Added test_ prefix as was thinking of using test sniffer.

#198 (not 210 after all): Always shut browser on error. Display exceptions in full to identify position of error. Improve failure printing.
Fixes #224 to make sure we only add the wdtk url if there are no other FOI contact details
#228 Functionally complete with no aesthetics yet.
#228 Fixed some aesthetics. Up/Down working in Individual and Timeseries cases.
#228 Enabling/disabling buttons as appropriate.
#228 Added up/down arrows to additonal_resources table
Fixes #199 sort by title by cleaning the title_string as well as title.

CKAN core lstrips the title in the pkg_dict, but it is the title_string that
is used for search, so this change in search_indexing attempts to clean
up the title string before insertion by lstripping whitespace and removing
puncutation where the title_string leads with it .. i.e. 'Ageing in the UK' dataset.
