CSS a bit to greedy

Just tried you plugin and it’s very nice.

However, I found an issue: the CSS-file for the plugin is added to all admin pages, which means that for example this rule:

table tr:hover{background: #EDEDED}

is applies to all tables in the admin.

It would be better if the css where only loaded on page where is was needed, and that is only targeted specific things.
