UI: Widgets are too wide in dashboard:"goals" and "advanced" table view should be disabled in the dashboard

[matt]

In the dashboard, currently the icons to show the "goal table" and the "advanced table" are shown; however when clicked, the table tries to display 5+ columns but there is not enough space, hence dashboard looks bad.

• disable icon for "advanced" and "goal" view in dashboard
• make sure all core widgets only have two columns. For example, the Actions widget should only show two columns; it currently shows "label, pageviews, unique pageviews" but could be "label, pageviews"

Optional: a link "view full report" could be displayed at the bottom of the widget, the link would open in ajax the report containing this widget; this requires:

• widget to know which report they appear on
• set the anchor the right widget in the report, in case the widget appears below the fold

A similar visual problem (from #649) can be created when the user increases the text size in the browser.
