Commit message: theme_adium_append_message: escape alias before displaying it

Not doing so can lead to nasty HTML injection from hostile users.

https://bugzilla.gnome.org/show_bug.cgi?id=662035
CVE: CVE-2011-3635
CWE: CWE-79
Vulnerability description: Cross-site scripting (XSS) vulnerability in the theme_adium_append_message function in empathy-theme-adium.c in the Adium theme in libempathy-gtk in Empathy 3.2.1 and earlier allows remote attackers to inject arbitrary web script or HTML via a crafted alias (aka nickname).
