Bug 18589: Show ILLs as part of patron profile

This patch moves the display of a patron's ILL requests to be inline in
the Patron Profile page, as per all other patron information.

It includes a substantial refactor of
koha-tmpl/intranet-tmpl/prog/en/modules/ill/ill-requests.tt in that it
moves the display of the illlist table (which is populated by an API
request) into it's own separate include file. It also moves the
datatable related Javascript for this table into it's own JS file. Doing
this allows us to reuse both in both the new members/ill-requests.tt
template and the pre-existing ill/ill-requests.tt template.

To test:
1) Ensure ILL is enabled and your user has sufficient permissions
2) Ensure your user has some ILL requests
3) Navigate to the user's patron profile page
4) Click on the "Interlibrary loans" tab
5) Observe that the requests table is displayed inline
6) Observe that only your user's requests are displayed

This is essentially a reimplementation of attachment 84796 to take into
account all changes that had happened beneath this bug and also to
ensure JS strings are translatable.
