This sadly came out as a combination of what I consider a bugfix and a feature patch:

FEATURE:

The attached patch adds a menu entry to access host's graphs. It's (hopefully) working everywhere this menu is available:

• Monitoring/Latest data
• Dashboard: Last 20 issues
• Monitoring/Triggers
• Monitoring/Events
• Monitoring/Overview – Hosts location: Left; Data and Triggers
• Maps

BUGFIX:

Sets groupid=0 for the menu entries screens, graphs, trigger status and latest data. I consider the original version bad, because it takes you wherever, if the hostid does not belong to the host group currently set in the filter.
