Screen Preferences locks refresh rate at single value for some monitors.

Description

When using older CRT monitors which do not provide the horizontal and vertical frequency ranges (EDID1_MONITOR_RANGES) in their EDID info, the Screen Preferences locks the refresh rate at the refresh rate of the current video mode. That is, the Refresh Rate drop down list shows only a single entry which is the refresh rate of the current video mode.

The attached diff file fixes this problem by setting the vertical frequency range to 60..85 Hz if the current range is zero which is the case when the EDID info does not contain this info.

When I filed this report, I neglected to fully state the problem with the Refresh Rate drop down list. When the refresh rate is clicked upon, a list with only one entry is shown which has the following text: "xx Hz/Other..." where xx is the current refresh rate. However, there should be two entries: "xx Hz" and "Other...". Clicking on "xx Hz/Other..." brings up the dialog box that should allow another refresh rate to be selected; however, that dialog box is empty. Thus, the dialog box is useless for selecting a refesh rate.
