Nils Adermann 2ee2701eb1 - introduce LA_, UA_ and A_ template variables (they allow styles to use template variables used for javascript in subSilver outside javascript in their own template while they won't break our javascript if they contain quotes) also fixes [Bug #1116] 
- corrected page title for search indexing progress bar [Bug #1695]
- correct poster name for the anonymous user in mcp_queue and mcp_reports
