[idd] driver; support custom resolution and refresh rate list

Custom modes can now be configured via the registry under

HKEY_LOCAL_MACHINE\SOFTWARE\LookingGlass\IDD

Create the value "Modes" as a REG_MULTI_SZ with the value as
a list of modes, for example:

1024x768@60
1920x1080@60
1920x1080@120*

The '*' denotes the preferred mode to default to if one has not
been selected by the user.
