* Re-wrote the IPR declaration form using form.to_table()
and the split_form() function in order to get sub-blocks
of the form which could easily be used with the existing
IPR detail display templates.
How to merge forms from multiple models took some thinking;
since the forms have a common ancestor, multiple inheritance
doesn't preserve the form data. In the end the merging
didn't turn out too horrible. See ipr.views.new().
* Changed the IprDetail model; first to specify editable=False
for all fieleds which shouldn't be shown in the form, but
this has the drawback of also removing them from the admin
page form. Simply bagging them in an un-used sub block with
split_form() works fine.
* Changed the URLs for IPR by-date some again
* Updated the ipr/new* templates to use the form sub-blocks
