Bug 12974 - Argument "" isn't numeric in numeric gt (>) in opac-results.tt

If an item has no star ratings you get an error message in opac-error.log:
Argument "" isn't numeric in numeric gt (>) at (...) /koha-tmpl/opac-tmpl/bootstrap/en/modules/opac-results.tt line 467.

To test:
In OPAC, search for a bilio that has no star ratings.
Check opac-error.log for message as above
Apply patch
Repeat search
Check opac-error.log again, there should be no more warnings

(Fixed mistake with brackets, see comment #2)

Works as advertized. Looks like you have to be logged in to trigger
the error.

Bug 12999: Untranslatable string on enhanced_content.pref

This patch modifies LangInstaller.pm to catch strings
on syspref files that have no associated syspref

To test:
1) Update strings for your preffered language
2) Check that the string "you can only choose one source"
is not present on xx-YY-pref.po file

3) Apply the patch
4) Update strings again
5) Check the strig now appears [ and another one :) ]

Doing a diff before and after will show
 # Enhanced Content > All
 msgid "enhanced_content.pref## <strong>NOTE:</strong> you can only
 choose one source of cover images from below, otherwise Koha will show
 the images from all sources selected."
 msgstr ""

 # Local Use
 msgid "local_use.pref## Nothing defined yet."
 msgstr ""

6) Translate the string
7) Install your language, check Administration > System preferences >
   Enhanced content > All
   (on your languge) and check the string is now translated
