Allow user to interact with --text-info --html WebView

This commit changes the default --text-view behavior (when --html
is also in effect) so that the clicked links are opened in the
default browser (closes #732626).

Additionally, a new option is introduced, --prevent-interaction,
which disables above behavior.
