input-forms.xml: Remove duplicate CCAFS form values
messages.xml: Personalize the LDAP login strings

Users have no idea what LDAP is, so let's try to make this a little
easier for them.
xmlui: verdana -> Verdana

Fix font names in all styles
xmlui: Fix font-family hierarchy

In case the user doesn't have Verdana installed, try for some other
sans-serif fonts, and then fall back on any "sans-serif" if need be.
xmlui: Clean up superfluous font declarations

Unneeded font-family declarations in base.css and style.css:

find modules/xmlui/src/ -iname "base.css" -exec sed -i "/font-family:/d" {} \;
find modules/xmlui/src/ -iname "style.css" -exec sed -i '16,${/font-family/d}' {} \;

This makes the fonts more standard and predictable, and also saves
parsing time.
input-forms.xml: Run through tidy

Standardize indentation and remove unneccessary white spaces using
tidy:

    tidy -xml -iq -m config/input-forms.xml

xmllint works too, but it reduces empty tags like <required></required>
to <required/>, which isn't as readable and could be confusing if
you go to modify the input forms and aren't someone who stares at
XML all day.
xmlui: Standardize colors for CCAFS buttons
xmlui: Standardize font sizes for CCAFS theme
xmlui: Standardize button colors for ILRI theme
input-forms.xml: Add BASELINE SURVEY subject focus for CCAFS
xmlui: Tweak font sizes for recent submissions

Was done earlier on ILRI and CCAFS manually, but now applied to
all with some git diff magic:

    git diff dspace/modules/xmlui/src/main/webapp/themes/IWMI/lib/css/style.css | sed s/IWMI/SLP/g | git apply

etc...
