Suggestion: number of checked items in javascript prompt

[ekenberg]

Suggestion: When doing any action with one or several checked rows that causes a JavaScript prompt (like "Enable selected actions?" or whatever), make the prompt also say *how many items* are checked. This is useful if you have very long lists and there might be checked items out of view that you're not aware of.

"Delete 15 selected triggers?"
"Disable 4 selected hosts?"
