input-forms.xml: Add subregions
inptu-forms.xml: Remove duplicate AFRICA region
input-forms.xml: Fix line wrapping in input-forms

It turns out that tidy wraps long lines, and this messes with the
metadata values stored by DSpace.  We need to tell tidy not to wrap
long lines by adding '-w 0':
    tidy -xml -iq -m -w 0 input-forms.xml
config: Use subscope search for LDAP

We want to search in all forests in the hierarchy.
input-forms.xml: Add new ILRI subjects
input-forms.xml: Add Indian states to subregions
input-forms.xml: Add Anancy subject list
input-forms: Correct stored values for some ILRI subjects
input-forms: Add TRYPANOSOMIASIS to ILRI subjects
Revert "input-forms.xml: Add Anancy subject list"

This reverts commit 71692085bf1af153815fdaa3fe3ee03962ab5926.

We're not ready for Anancy subjects yet, we will add them in the
new cg schema.
dspace.cfg: Disable webui.browse.thumbnail.*

Despite their names, they are only used in JSPUI, so we can disable
them.
config: Add special group for users logged in with LDAP

When a user logs in with LDAP, we add them to a special CGIAR group
automatically; this way we can do things like limit access to items
or bitstreams.
