[jan] Don't show admin alarm form if alarms are disabled.
[mms] Fix iteration of Horde_Prefs_Scope object.
[mms] Add 'tlsv1' as a secure parameter option in the Client constructor.
[mms] Fix prototype.js issue in IE 9 regarding array iteration in a parent window.

Merge branch 'master' into imp_6_2
